7. General information on heartbeat and heart rate variability
Our hearts keep us alive and work tirelessly throughout our lives. It pumps the blood through our body, so that oxygen-rich blood penetrates all the parts of our body and oxygen-poor blood is enriched again in the lungs with fresh oxygen. But it also keeps everything moving, including the transport of nutrients, hormones, immune cells, etc.
It is easy to know that our heart is beating, you can feel your pulse or even hear it when you put one ear to the chest of another person. Since time immemorial, we have been studying and measuring the functions of the heart and measuring the heartbeat is essential.
Depending on the situation, our heart is able to regulate the heartbeat. When we sleep, it usually beats slowly and evenly, when we exercise, it beats fast and adjusts its frequency constantly. Depending on the creature, the resting pulse changes: only six heartbeats per minute for a blue whale and 1,000 heartbeats per minute for a shrew. We humans lie with approximately 60 heartbeats per minute in the lower range, infants have a faster resting pulse of approximately 130 beats per minute. With great effort, our heart can also beat at over 200 beats per minute.
Heart rate variability (HRV) refers to the ability to change the frequency of the heart rhythm. Even at rest, there are spontaneous changes in the time between heartbeats.
Our body has a multitude of regulatory mechanisms to change the heart rhythm. Two essential components are the sympathetic nervous system, which activates and accelerates the heartbeat, and the parasympathetic nervous system, which acts as a brake to slow down the heartbeat.
A healthy person constantly adapts the heart rhythm to current requirements. In addition to physical exertion, such as sport or physical work, psychological exertion such as stress also results in an increase in the heart rate. The heart rate sinks again when the strain is relieved and the body relaxes. In humans, heart rate variability ranges from 10 (low, a sign of stress) to 30 (high, a sign of relaxation).
The more our body is able to regulate the heart rate (the greater the heart rate variability), the healthier we are. If the heart beats only rigidly, a person is about to die.
The measurement of heart rate variability is a large field in cardiology and is used for extensive diagnostics. With the eSense Pulse, we want to focus on biofeedback training, i.e.improving heart rate variability. To describe the current state and progress of the training, the eSense app also provides the essential statistics and analyses of HRV.
We combine the measurement and feedback of heart rate variability in the eSense app with guided relaxation exercises and guided meditations and offer you an overall experience that goes beyond biofeedback. In addition to extensive feedback variants, you have the option of evaluating your measurements with many statistics, documenting your progress and exporting the recordings as CSV and PDF files. Your data belongs only to you! You have full access to the raw data.
8. Features of the eSense Pulse
The eSense Pulse is a pulse sensor that uses a smartphone/tablet and an app to accurately measure heart rate variability. We focus not only on measurement, but also on biofeedback training to improve your heart rate variability and health!
The eSense Pulse with the eSense App offers you:
9. Explanation of the individual measured values
Score (developed specifically by Mindfield)
For the Mindfield app, we have developed our own score system. This score, developed by us, should simply tell you how good your heart rate variability is with just one number.
Simply put, the better your heart rate variability, the higher this value.
In detail: The score is the sum of the regularity of the curve (in percent) and the amplitude (absolute value) divided by the rate of data from eSense Pulse (which transmits the last measured values via Bluetooth® every 200 ms) plus the previous score.
Whereby the time interval between Score and Score0 is just 200ms. If Regularity Percent << 90 then:
Thus, especially measurements of the same duration can be compared well (for example, if you always set 15 minutes as the measurement duration in the settings), since a higher regularity of the curve and / or a higher amplitude but constant time results in a higher value.
Regularity (developed specifically by Mindfield)
We also included the regularity as another value. This is also recorded by a formula developed by us and displayed in color (from a measurement duration of 5 minutes or more) in the overview after the measurement:
Attention: The colored coloring of the regularity does not correspond 100% with the color distribution in the pie chart as these are detected in different ways.
For the background coloring of the oscilloscope, a period of 20 seconds is taken and it is determined which regularity value is the most common color.
The pie chart, on the other hand, uses all the numeric regularity values of the entire session, with the percentages in red, yellow, orange, and green taken from them.
General HRV values
As an introduction to all measured values, we would like to briefly point out that the terms RR and NN mean the same thing but are used alternately in science and literature. The RR or NN interval is the distance between two heartbeats, in milliseconds.
Put simply, you train as much variability as possible between these intervals. The analysis of this distance data is possible in different parameters, which allow for different conclusions about the condition of your nervous system.
Time-based measured values
To get a feeling for this value, just think of the following three examples: If you have a resting pulse of 60 beats per minute, the average RR is exactly 1,000ms or one second (since one beat per second). If you are doing light to medium physical exertion at 120 beats per minute, then the RR is 500ms, or half a second (since two beats per second). If you’re working very hard to get your pulse up to 180 beats per second, the RR is 333ms or a third of a second (because three beats per second). For this value, there is no better or worse, the bigger or smaller. The only statement that can be made is that the higher the value at rest, the slower your resting pulse, which, for example, is a sign of fitness and a strong heart muscle in endurance athletes.
Frequency-based measured values (available as in-app-purchase)
In addition to the time parameters, we have also integrated frequency-based parameters into the analysis. A Fast Fourier Transformation is performed during each measurement from start to finish. You can observe the resulting spectrogram during the measurement in the last slide in landscape format.
LF / HF ratio
10. Introduction to eSense Pulse
There are various methods for measuring the heartbeat. With the eSense Pulse, we have decided on a chest strap that performs a 1-channel ECG measurement. There are two electrodes in the chest strap which require good, direct skin contact. The chest strap must always be worn under clothing.
In order to ensure a good contact between the electrodes and the skin, the enclosed electrode contact spray or an equivalent electrode gel should be used. Without it, the heartbeat sensors will not take sufficient measurements, which makes a precise HRV measurement difficult. For more information, see the article about the open training.
The eSense Pulse uses a 500 Hz sampling rate (500 times per second) to determine heart beats and wirelessly transmits the time between two heart beats to your smartphone/tablet and the eSense App in milliseconds via Bluetooth®. Compared to the normal electrocardiogram (ECG), in which the waveform is very important, the measurement of heart rate variability focuses on the temporal resolution of the RR intervals.
With this data, the eSense App can then perform various calculations, such as determining the heart rate (beats per minute or, colloquially, the pulse), the heart rate variability with various analysis parameters and biofeedback training. In the article explanation of the individual measured values, all parameters of the eSense App and their meaning are explained clearly.
It also important to note that heart rate variability benefits respiration. Of particular interest is the coupling of heartbeat and respiration in order to determine the degree of coherence or synchronization of heart rhythm and respiratory rate. This is also done in the eSense App.
The heart rate increases when inhaling and decreases again when exhaling This phenomenon is called respiratory sinus arrhythmia (RSA) and is used to check the balance of the nervous system. Biofeedback training in the eSense App uses this phenomenon to improve heart rate variability with the help of a breathing target.
Regular biofeedback training with the eSense Pulse has a positive effect on heart rate variability and RSA, and both have a positive effect on a number of stress-related problems. Bring your nervous system back into balance!
11. Operating instructions for the eSense Pulse
Contents of the packaging:
Remove the eSense from its packaging. Put on the chest strap as shown and adjust it to the correct length.
The strap should be tight, directly under the chest muscles, but not uncomfortably tight or squeezed. Once you have adjusted the belt, remove it again to apply a small spray of the enclosed electrode contact spray to each electrode. This surface separates the two electrodes from each other! No “bridging” may occur here.
This process significantly improves the conductivity and the ECG signal becomes clean and precise. Put on the belt again and press the eSense Pulse Sensor on the two push buttons. Make sure that the eSense logo on the front is not upside down for a person looking at you. You will also find an “L” for left and an “R” for right on the push buttons on the sensor.
Now the eSense Pulse is ready to use and can be connected to the eSense App. In case of any connection problems, briefly remove the sensor and reconnect it to the belt. This will switch it on and off. To prevent the battery in the sensor from being used up unnecessarily, always disconnect it from the belt when not in use.
Battery Change & Battery Information
The battery has a service life of approx. one year if used regularly. You can read the current state of charge in the eSense App. A replacement battery type CR2032 is available in our online shop or in any electronics store. Dispose of a used battery professionally and not in the household waste. Batteries are very dangerous if swallowed. For this reason, keep batteries and small parts away from children. If a battery has been swallowed, consult a doctor immediately.
To change the battery, open the battery compartment by turning it counterclockwise with a coin. The battery is facing up with the positive pole. Insert the new battery and close the battery compartment again by pressing on the cover and turning it clockwise for a short time.

12. Heart Rate Variability and Biofeedback Training
In order to reduce stress and its symptoms, biofeedback training can be performed seeking to increase heart rate variability.
Biofeedback training is quite applicable to heart rate variability In stress medicine and psychophysiology, HRV biofeedback is used for depression, heart disease, asthma, anxiety disorders and insomnia. HRV biofeedback is also widely used in coaching and competitive sports. Improving HRV and the connection between breathing and the heart can help relieve tension, cope with stress and anxiety, and contribute to a more relaxed response in everyday life. If you suffer from a serious disorder or medical condition, always consult a professional physician or therapist, and do not attempt to treat yourself. The eSense Pulse is not a medical device and may only be used to reduce stress.
The eSense Pulse is a very precise device. It can record heartbeats and display them, for example, as a measurement curve. Take a look at the following example of a measurement at rest and with even, slow breathing:
As you can see in the example above, the curve is a distinct sine wave and the amplitudes are very uniform.
The aim of HRV biofeedback is to increase heart rate variability, specifically its amplitude. In other words, to maximize the difference between low heart rhythm and high heart rhythm in the interplay of inhalation and exhalation, rest and demands. Under demands and with uneven breathing,
HRV and its curve shape decreases significantly, as shown in the figure below:
In the above example, the curve is uneven, and the deflections are different. Especially from 6:30 and 6:50 the line is almost horizontal with almost no amplitudes.
If respiration is included, the eSense App offers various ways to visualize it and to define respiration in a certain rhythm. The coupling of heartbeat and respiration is greatest in most people when breathing at about 4.5 to 6.5 breaths per minute.
In the eSense app, you can do a free training or complete predefined procedures. The amplitude of HRV is measured and an increase is providing positive feedback, while a decrease provides negative feedback. A change in breathing is also linked to feedback.
 Lehrer, P. M. (2013). How does heart rate variability biofeedback work? Resonance, the baroreflex, and other mechanisms. Biofeedback, 41, 26-31.
For feedback, there is, for example, a video, that continues to run in the positive case (stops in the negative case), music, whose volume changes, tones, which change pitch, vibration of the Smartphone and much more. Of interest is the function for controlling a smart light bulb (Philips Hue or Magic Blue), whereby heart rate variability is reflected in the change in color and brightness of one or more lamps. You can use your stress level to illuminate an entire room.
A biofeedback training consists of four training stages. Plan about 60 to 90 minutes for the first session, during which you can do the training undisturbed and in one session. Detailed instructions can be found in the chapter, “Training sequence.”
A procedure consists of different modules. The procedures can be used, for example, to implement instructions for relaxation, a stress test, a defined biofeedback training session or tasks for research purposes.
The possibilities are manifold. During a procedure, your heart rate variability is naturally recorded. At the end of a procedure, a summary is displayed, showing your readings for each module and the overall view.
We recommend that you try the demo procedures included in the app. These give you a guided overview of the different modules and functions.
The included procedures are also protected by a password in order that those can’t be edited or deleted by accident. You can any time create a copy of those procedures without a password and change it as you wish.
We also explain in detail how you can create and edit your own procedures in the chapter procedures settings.
14. Open Training
As a second option you can also conduct an open training. This is compared to the procedures a bit more complex. We therefore explain a typical open training session which consists of 4 training phases.
Preparation and start
First stage (observe and experiment; determine your initial status)
Second training phase (targeted biofeedback training based on the measured values)
Practice an increase in heart rate variability, including the breathing aid. You can activate the breathing aid in the app settings, it is not active by default. Activate it and start breathing training at your usual breathing rate. This will, in most cases, be between 12 and 15 breaths per minute. This is faster than quiet breathing during deep relaxation. However, it is easier to start with your “normal” breathing first and then gradually slow down your breathing pace to below 10 breaths per minute. Set the inhalation and exhalation times in the breathing target as desired. (For 15 breaths, set 2 seconds for inhalation time and 2 seconds for exhalation time, or 3 seconds for inhalation and exhalation time if you want to try 10 quiet breaths per minute). It is helpful to breathe out a little longer than in.
Third training phase (provocation, relaxation and stress management)
Fourth training phase (transfer, relaxation even without feedback)
15. Kubios HRV Software
The Kubios HRV Premium Software offers you detailed HRV-analysis with its over 40 analysis parameters and can be perfectly combined with the eSense Pulse.
Analysis of your measurements with Kubios
Some parameters (e.g. SDNN, RMSSD, pNN50) are measured different in the eSense app than in the Kubios software. You can adjust the settings in Kubios so that the data are identical. To do this, you must set the “Artifact correction method” and the “Detrending method” to “none” (marked in yellow below):
16. Smart Bulbs (optional)
The eSense app can support biofeedback via smart bulbs. Smart bulbs can change their colors and brightness and can be controlled via Bluetooth®. In combination with the eSense app, smart bulbs indicate your level of stress or relaxation through their lights.
Currently, the eSense app supports the Magic Blue and Phillips Hue smart bulbs. Both are smart bulbs which can be controlled via Bluetooth®. The color as well as the brightness can be adjusted. From within the eSense App, you can connect to the Magic Blue or the Phillips Hue and use it in your biofeedback session. Here you connect to the Hue Bridge from the eSense app and select the desired lamps.
Unfortunately, the Magic Blue is no longer in production. In the future, however, it will be replaced by another Bluetooth solution for smart light bulbs.
But you still can find more information about the Magic Blue in our article
You should be able to find the Phillips Hue in every well-sorted electronic store. You can also order it online. A list of the on- and offline-merchants can be also found on the page of the Phillips Hue: https://www.philips-hue.com/en-us
We suggest you use one of the starter kits from Phillips, with the eSense. This also contains a colored bulb (‘Color Ambience’): https://amzn.to/3uzSFx8.
You can also find more information about the Philips Hue in our article.
17. Functions of the Mindfield eSense App
The eSense comes with the eSense app which you can load for free in the Google Play Store (Android) or Apple App Store (iOS).
It offers a wealth of features for effective biofeedback training in a modern design. Essential functions are: the display of measured values as a bar graph, an oscilloscope, feedback via video, music, sound, vibration, and smart bulbs (Magic Blue and Philips Hue). You receive a comprehensive evaluation after each measurement and can compare measurements with each other in the archive and export them as CSV files.
The app is available in English, German, Spanish, French, Italian, Portuguese, Ukrainian, Russian, Turkish, Dutch, Japanese and Chinese. The language is chosen automatically according to the set language of the smartphone or tablet.
18. General notes
In following the app is described in full details.
19. General view & Open Training
20. Breath Pacer
Breathe as the sphere expands. With growing ball breathe in, with shrinking ball breathe out. The coherence (here 68%) shows you how much your heartbeat follows the breathing, the higher the value, the better. 100% cannot be reached.
Once you are over 50%, there is a correlation between heart and breath. Try to get as high a value as possible and experiment with different breath time specifications.
21. Biofeedback Snake
You can also display the Biofeedback snake as an additional option. At the top left are appearing symbols which vary in color depending on the current measured value.
After 10 green symbols you will also be rewarded with a star and after 50 green symbols even with a shooting star. If the snake goes over the entire screen you will see the last 5 minutes.
The spectrogram shows how often the respective RR intervals (also NN intervals, the distance between two heartbeats) occur. This provides information about the proportion of sympathetic and parasympathetic heartbeats.
The spectrogram shows frequency bands from 0.04 to 0.4 Hz. The number of RR intervals of each frequency band is counted and plotted on the spectrogram. The skin-colored range shows the low RR intervals (0.04 Hz – 0.15 Hz, sympathetic range) and the purple range shows the high RR intervals (0.15 Hz – 0.4 Hz, parasympathetic range). The spectrogram is calculated using a Fast Fourier Transformation (FFT).
Simply put, with this graph, you can see how even the RR intervals are. Optimally, you have only one (or a few) distinct peak(s) in the skin-colored area and only one (or a few) distinct peak(s) in the purple area. This indicates that your RR interval repeats regularly in both the low (sympathetic) and high (parasympathetic) frequency ranges without large deviations.
Further information on the RR interval (NN interval) and the significance of the low and high frequency ranges can be found under “Explanation of the individual measured values” in this manual.
23. Survey (optional)
If you have activated this option in the general settings, a small survey will appear immediately after each measurement. This allows you to archive measurements that are reproducible in the long term or to document a change in your measurements. (If you for example start to use the eSense while lying down instead of sitting down).
Your position during measurement
How do you feel?
Note function, optional
24. Pie chart (after the measurement)
After the measurement (and optional questioning), in landscape format, a screen appears with a pie chart: The time in percent of the regularity of your HRV curve. In addition, additional values from the entire measurement are listed for you again.
At this point, you can also swipe the screen to the left or right to switch between the pie chart and the graph of the measurement.
25. Procedure Overview

29. Creation of a procedure
You can also choose one of our guided meditations as a procedure. The breathing meditation is already included in the eSense app.
We will also offer more meditations shortly as new free cloud procedures for users with account. The meditations thus offer you an easy way to train your awareness and attention and, at the same time, receive biofeedback.
31. Own media (photos, videos and audios)
You can use your own pictures in the picture module, your own videos in the video module or your own music or melodies in the audio module in the procedures.
Android usually enables this without any further problems. As long as you allow the eSense app to access your files on your device, you can upload them to the eSense app.
iOS is a bit more restrictive. As usual, you can use your pictures from your device in the iCloud for pictures and videos.
For audio files you need iTunes (or an alternative such as “CopyTrans Manager”). This is where your music or melody must be. You can find your music in iTunes (or CopyTrans Manager) under the tab “My Sound” and insert it into your procedures.
We have a detailed video at https://www.youtube.com/watch?v=A_CRbmBeBBc where we show all the steps.
On iOS the power saving mode must also be deactivated, otherwise the videos in the procedures cannot be played.

34. Archive (overview)
The app also contains an archive, in which you can save your measurements and export them as well. You can watch those in detail again, compare them to each other and export them individual or all together (as ZIP file).
If you click on the clipboard symbol at the top right, you can mark one, several or all measurements. You can then export, analyze or delete the exported measurement (s).
On the filter symbol you can choose whether you want to sort the measurements by name, date, length in ascending or descending order.
If you want to delete a single measurement from this list, you can also tap on the trash can symbol to the right of the measurement.
Time, score, average of session HR, minimum HR, maximum HR, difference min/max HR, SDNN ms, RMSSD ms, NN50, pNN50 %, stress index, average RR ms, Average HR.
With this, you can recognize trends over time and over several measurements (if, for example, your % of SCR of Session decreases by regular training, you can see this here immediately).
35. Archive (single view)
If you click on the export symbol on the top right, you can export the measurements as a .csv-file with all common apps (for instance, send over the Messenger, WhatsApp, email, etc.) or simply save them on your device or in your cloud.
The data are exported as a.csv-file (comma separated values). This format can be opened with Microsoft Excel or Open Office Calc (for free).
If you like to work with Google, Google Sheets can be an alternative to Excel for you. You can open your exported .csv-files, visualize and access them via the cloud easily from several devices. Google Sheets has almost the same functions and interface as Excel.
Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data.
Regularity in % of the HRV curve
You can see here also the Regularity of your measurement. This pie chart is the same as the one you see after the measurement. You can get more information about the regularity in the chapter ‘Explanation of the individual measured values’ in this manual.
In Excel™ or Google Sheets™
Notice: If you open the .csv-file with Excel™ (or Google Sheets™) and your values make no sense, then there is usually a different set language in the eSense App and Excel™ and Sheets™.
Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data.
36. Marker feature
You can also set markers while you make measurements. For example, if you have a regular biofeedback exercise which involves breathing calmly at a specific point, you can set a marker in that moment when you breathe calmly. Later in the exported data, you can see the moment where you had breathed calmly. The marker feature comes in handy when you are making longer measurements with several actions.
The markers can be displayed well in Excel:
37. Compatible Android and iOS devices
Note for all eSense:
If you don’t have a device yet and/or want to buy an extra device for the eSense, we recommend depending on your taste either
According to our research, these options offer enough power for the eSense app, will remain upgradeable to the upcoming Android and iOS versions for some time, and are still reasonably priced. The Android devices also still have a normal 3.5mm jack input and do not require an adapter for the eSense.
iOS devices compatible with the eSense
Additional note Siri:
Note for iOS devices and the eSense Pulse:
Note for iOS 7 and later and the eSense Respiration, Skin Response, and Temperature:

Important note about Android devices for the eSense Pulse:
Important note about Android devices for the eSense Respiration, Skin Response and Temperature:
Alternatively, you can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1.
Below are some Android devices that we have tested with the eSense Pulse, Respiration, Skin Response and Temperature and which work fine (whitelist). (Please note that this is only a very small sample and that the vast majority of devices worldwide work with the Mindfield eSense).
The following Android devices are NOT compatible with eSense Respiration, Skin Response and Temperature (blacklist). This list is not necessarily exhaustive. If you are not sure if your device is compatible, check if the microphone input is present as described above!
It is possible that these devices will work after all if you use the devices’ USB-C port instead. You can use a USB-C to 3.5 mm jack adapter for this purpose: https://amzn.to/40eCoLR.
38. eSense Web App
In addition to the app, we have also developed an eSense web app that mirrors and supplements the app. You can use this with the account and plans mentioned above.
You can analyze your recorded data (with the basic plan) or even transfer your data to a PC in real time (live streaming with the premium plan).
The main advantage of this is that you can see the graph even better with a large screen and enlarge individual areas and have more advanced analyze features.
With the eSense Web App, you can also view measurements from several and different eSense simultaneously and in real time, which allows a professional trainer client to design the workflow.
You can find the web app at https://esense.live. There you can login with the same account (username and password) as for the eSense app. For more information on the eSense Web App and its capabilities, see also our article on streaming eSense data.
The eSense App is working for the eSense Skin Response, Temperature, Pulse and Respiration. It’s not supporting the eSense Muscle.
39. Account and Cloud
You can register your own, free account for the eSense app and book plans. You can also benefit from free, regularly added procedures without booking a plan. Thus, we recommend using the app with an account. With the plans you can mainly use the cloud and its functions and get also access to the eSense web app at https://esense.live.
With the Basic plan, you can save your measurements locally and online in the cloud and thus access your measurements from all devices and from anywhere. You also get access to the eSense web app.
The Premium Plan includes all functions of the Basis Plan. In addition to your measurements, you can also save your custom procedures online in the cloud and thus access your procedures from all devices. (Attention: Technical limitations from Apple unfortunately do not allow the upload (and thus the synchronization) of audio files. The synchronization of picture and video files is possible, however).
You can also share your measurements with other users as Premium plan user. You also have the option to live stream your data to the eSense Web App in real time. To do this, activate “Real-time data transfer to eSense Web App” in the settings at the bottom.
These plans can be used, among other things, to design a trainer’s client’s workflow. You can find an overview of the account and the cloud in our account comparison article.
You can book the plans in our app in the profile tab:
Plans in profile tab
The accounts enable you to create your own groups or to join other groups. This allows you to share your recordings with your friends. Or you can work with a trainer as a client since you can share your recordings with the trainer.
Create a group
Tap on the plus symbol to create a group.
Edit a group
Tap on the 3 dots next to the group name You can then (if authorized) view and remove the members of the group or add new members.
The eSense App does not collect any personal data, such as name, gender, date of birth, etc.. Each recording of measurement data is done under a general prefix such as “measurement”,
supplemented by with the eSense sensor used, the current date and time of the measurement. The recorded measurement data cannot therefore be assigned to any person.
The prefix of a recording, e.g. “measurement”, can be changed by the user in the settings and used for the assignment to a person. Users can decide whether to change this prefix to their name, for example. Then each measurement and also each CSV file exported from it contains the name of the user in the file name.
Access rights within the eSense App
Transmission of anonymous usage data and crash reports
In order to improve the technical stability of the eSense App and the detection of code errors, we use the Sentry service. Sentry serves these purposes alone and does not evaluate any data for advertising purposes. The transmission takes place anonymously and only with an existing internet connection.
