La cohérence cardiaque rencontre un succès croissant auprès du grand public et des professionnels de santé. Préalablement appliquée en prévention cardio-vasculaire, elle est de plus en plus utilisée dans les programmes de gestion de la réponse émotionnelle, du stress et de l’anxiété.
Face aux sollicitations stressantes de la vie quotidienne, la cohérence cardiaque renforce l'adaptabilité du système physiologique d’autorégulation pour lutter contre les problèmes psychologiques et physiques, permettant ainsi à l’organisme de maintenir un meilleur équilibre intérieur.
ROLE DU SYSTEME NERVEUX AUTONOME (SNA)
Originaire du cerveau limbique, siège des émotions, le système nerveux autonome permet :
- le contrôle des principaux organes : yeux, cœur, poumons, estomac…
- l’homéostasie : régulation et maintien de l’équilibre et de la stabilité physiologique.
Le SNA est composé de 2 branches agissant de façon contraire comme une balance dynamique :
- le système nerveux sympathique : associé à l’action, il met l'organisme en état d'alerte et le prépare à l'activité.
- le système nerveux parasympathique : associé au repos, il ralentit les fonctions de l’organisme et conserve l’énergie.
Un SNA flexible permet à l’organisme de maintenir l’homéostasie, face aux sollicitations stressantes externes (environnement) et internes (émotions, douleur…). A l’inverse, le manque de flexibilité expose à différentes manifestations somatiques et psychologiques.
Les études cliniques récentes soulignent qu’un SNA rigide s’explique principalement par un moindre tonus du système nerveux parasympathique, aussi appelé tonus vagal.
DIMINUTION DU TONUS VAGAL ET PATHOLOGIES
Ces études montrent une diminution significative du tonus vagal chez les personnes :
- diabétiques, hypertendues, asthmatiques ou encore atteintes de maladies inflammatoires ou douloureuses chroniques ;
- stressées ou présentant une anxiété chronique, une anxiété généralisée, des crises de panique ou un état de stress post traumatique.
Différents mécanismes déclencheurs, aujourd’hui mieux connus, sont en cause : des phénomènes de régulation réflexe entre la fréquence cardiaque, la respiration et la tension artérielle ainsi que des mécanismes neurobiologiques du cerveau liés au stress et aux émotions.
AUGMENTATION DU TONUS VAGAL
Il existe une façon simple et accessible à tous pour agir sur le tonus vagal : la respiration.
L’entraînement régulier au contrôle respiratoire permet en effet d’optimiser ce système réflexe - aussi appelé baroréflexe - reliant la fréquence cardiaque, la respiration et la tension artérielle.
En cas de diminution ou d’augmentation de la tension artérielle, les récepteurs de nos vaisseaux sanguins déclenchent par l’intermédiaire du SNA une accélération ou une diminution de la fréquence cardiaque.
Ce phénomène physiologique régulateur peut être optimisé en respirant à une fréquence de 6 cycles par minute (cpm) : inspiration=4,5 secondes et expiration=5,5 secondes.
Cette respiration lente, régulière et guidée, permet de mettre en résonance les variations dues à la respiration avec les variations dues à l’activité baroréflexe, renforçant ainsi le tonus vagal et maximisant l’adaptabilité du SNA.
Cet état de résonance est appelé cohérence cardiaque.
Le travail de cohérence cardiaque augmente le tonus vagal et renforce la flexibilité du SNA, permettant ainsi à l'organisme de maintenir une meilleure homéostasie et de mieux lutter contre les problèmes psychologiques, physiques et psychosomatiques.
La bibliographie scientifique récente nous en démontre tout l’intérêt pour :
- mieux adapter la réponse émotionnelle face au stress
- prévenir les risques d’infarctus
- augmenter les capacités pulmonaires
- diminuer les troubles respiratoires
- soulager la fibromyalgie
- réduire les douleurs physiques perçues
- améliorer les états dépressifs et l’anxiété
- diminuer l’hypertension artérielle
BioZen was developed as a pilot project to study the feasibility of using smartphones to receive signals from biosensor devices. The National Center for Telehealth & Technology (T2) is a Department of Defense organization that evaluates new technologies for telemental health. BioZen represents an approach to mobile monitoring of biosensor devices that may be further developed to support future projects. No further development or enhancements to BioZen are planned.
Using BioZen requires compatible biosensor devices (see listing below). These devices and BioZen are not designed or intended for psychological therapy or medical treatments.
BioZen can display several brain wave bands (Delta, Theta, Alpha, Beta, and Gamma) separately, as well as combinations of several bands using algorithms that may indicate relevant cognitive states, such as meditation and attention. BioZen features a meditation module that represents biometric information with user-selectable graphics that change in response to the user's biometric data.
Biofeedback data is recorded in real time, so users can observe relationships between recorded biophysiological data and their behavior. Users' can create notes to document and categorize their recording session. BioZen automatically generates graphical feedback from the recording sessions to allow users' to monitor their progress over time.

Purpose of App:
1) Lower your high blood pressure.
2) Help with insomnia and aid with better sleep.
3) Reduce your daily stress and make you calmer and your life more peaceful
4) Help relieve your stress and depression.
5) Make you more focus for your study and work.
6) Useful in managing headaches and migraines.
7) Slow, deep breathes can also help with pain management.
8) Help you with better mediation.
How to use it:
1) First time users should go through 15 minutes training session to find the most comfortable breathe pace. Cover your back camera lens with your finger completely. You don’t have to cover your LED but should make sure the light is strong enough to help camera to read your pulse.
2) After you know the most comfortable breathe pace, go to settings and set the breath pace to your comfortable level. Also you can set practice timer for your practice session.
3) Use your finger to fully cover phone’s back camera lens. Make sure LED is lighting your finger from side as closer as possible. The detected heart rate should be pretty constant. If you see your heart rate changes too high or too low, you probably didn’t fully cover lens with your finger. If your finger feels too hot, you can use small plastic glass glue to back of your phone to cover your lens and LED.
4) Remember the whole purpose of the practice of deep slow breathing is to achieve coherence with your nerve system through your smooth breath with concentration. Usually it takes a couple minutes to adjust your breath to get to the calm stage.
5) The suggested practice time is two, fifteen minutes session a day to achieve around 200 points. The ideal breath pace is from 5 to 6 breath per minutes to achieve coherence. If you follow the recommended practice time, you should feel and see results after six weeks of practice. Use your breath practice in your daily live.
6) This is not medical device. You needs consult your doctor to change dose or stop your medication if you see your high blood pressure dropping.
The Android phone has to be Galaxy II equivalent or up. The pulse detection is heavily reliant on the camera’s speed and phone’s process power. The application on the App Store for the iPhone is coming soon.

HRV Logger requires at least Android version 4.3 and Bluetooth 4.0. HRV Logger was tested using Polar H7, Armour39, mio alpha and two Samsung S3 (i9300 and mini) running android 4.3.
The time window used to compute features can be configured choosing between 30 seconds, 1, 2 or 5 minutes. Windows of at least 2 minutes should be used when using low frequency features (LF). Given the non-constant frequency at which RR-intervals are received, a buffer of RR-intervals is used to collect 30 seconds to 5 minutes of data, on which features extraction is executed.
The following features are extracted from RR-intervals:
- Mean of beat-to-beat intervals (AVNN),
- Standard deviation of beat-to-beat intervals (SDNN),
- Square root of the mean squared difference of successive RRs (rMSSD),
- Number of pairs of successive RRs that differ by more than 50 ms (pNN50),
- Low frequency power (LF, 0.04-0.15 Hz),
- High frequency power (HF, 0.15-0.40 Hz),
- Low to High frequency power ratio (LFHF).
Since RR-intervals come at non-constant frequency, they are linearly interpolated before frequency analysis. After interpolation, a hamming window is applied.
RR-Intervals correction prevents artifacts due to ectopic beats or motion from affecting features computation, as often reported in literature for HRV analysis.
It is advised to keep RR-interval correction to 20%, meaning that every RR-interval which differs by more than 20% from the previous one, will be discarded. HRV Logger provides three options, the correction can be completely disabled, in case you are interested in looking at PVCs or other events. By default the correction is set to 20%. The third and last setting is 50%, which is a less aggressive correction, since every RR-interval which differs by more than 50% from the previous one, will be discarded.
All files are in csv format, making it easy to import them in other tools. Four files are exported for each recording, including timestamped HR, RR-intervals, extracted features and annotated events.
Overview on HRV:
The cardiovascular system is mostly controlled by autonomic regulation through the activity of sympathetic and parasympathetic pathways of the autonomic nervous system. HRV analysis attempts to assess cardiac autonomic regulation through quantification of sinus rhythm variability. The sinus rhythm times series is derived from RR intervals (R peaks of the QRS complex derived from the electrocardiogram (ECG)), by extracting only normal (NN) intervals.
Since HRV aims at quantifying autonomic regulations, it can be used as marker of sympathetic or parasympathetic predominance, and therefore become relevant in many applications. In athletes for example heavy training is responsible for shifting the cardiac autonomic balance toward a predominance of the sympathetic over the parasympathetic drive, and HRV analysis attempts to quantify this shift.
Other applications span from stress monitoring during public speaking or daily life, assessment of pathological conditions and even emotional regulation during financial decision-making (trading).

Its aim is to deliver information on the management of cardiovascular risk before noncardiac surgery.
There is also a practical protocol to assess whether a patient requires cardiac evaluation before noncardiac surgery.
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat (called R-R) intervals.
The metrics calculated at the moment are: SDNN, RMSSD, pNN50, AVNN.
To use the application you need a Bluetooth Low Energy heart rate monitor. We have personally tested the application with the Viiiva, Wahoo BlueHR and Polar H7 heart rate monitors.
The Viiiva is available at our store: http://store.selfloops.com/viiiiva-heart-rate-monitor-and-ant-bridge/
If you record the session you will be able to export the data, saved in csv format, to Dropbox, Google Drive, by email etc, and open it using Microsoft Excel, a text editor, Apple Numbers.
By using the application you expressly agree that SelfLoops is not providing medical advice with this application. Please, consult or ask for the advice to your physician or other medical professionals for any health related questions.
For an intro to HRV see: http://en.wikipedia.org/wiki/Heart_rate_variability
Getting the balance just right between recovery and training is often a challenge, even for the most experienced athletes. Therefore, it makes sense to use an app, which removes the need for guess work or complex calculations from your training schedule. By using ithlete you will have accurate data and be able to quickly and easily measure your daily fatigue levels as well as your recovery levels.
Benefits of using ithlete:
• Know when to train, how hard to train and when to rest
• Optimise every training session for improved performance
• Enjoy guilt-free rest days
• Avoid overtraining & prevent injury
• Track long-term progress
Who wouldn’t want to improve their training and performance?
How it Works
Simply take a 1 minute measurement every morning with ithlete and follow the colour coded training recommendation; train as normal, train light or take a rest day.
Training is all about stress and recovery and a hard session will lower your HRV. If this stays low, even with rest, you could be in trouble.
The human heart is a naturally great barometer for measuring your physical and mental condition. Heart beat intervals vary when you are resting (many people do not know this) and a HRV captures this valuable information. Increased HRV is linked to good health and a high level of fitness, whilst decreased HRV is linked to stress, fatigue and even burnout. This is why measuring HRV is a must for all athletes, whether professional or keen amateurs.
The ithlete HRV app requires additional hardware. Users will need either a heart rate monitor chest strap and ECG receiver or a Bluetooth Smart HRM strap. Both are available from www.myithlete.com/products.
*Device must support Bluetooth Low Energy and be running Android 4.3 or above
N.B. - Whilst the ithlete app supports Bluetooth Smart you must have a compatible device and be running the latest Android software (4.3 or above) to use a Bluetooth Smart HRM strap.
Please also note the HRV app is NOT the same as a heart rate monitor app, which people use during exercise. The HRV app is an app that uses heart rate variability to diagnose your state of fatigue, recovery and readiness to train and is not used during actual exercise.
The process is simple:
Select or search for a specific ailment within the app
Select the time desired
Select START and listen to the powerfull RIFe Audio frequencies as they begin to address imbalances in the body.
Since the 1930's there have been many books, articles and newspapers published concerning Rife's Research on Cancer and other diseases. Most of his lab notes have long been forgotten about, destroyed or kept under lock and key by a few individuals.
Interest in Rife's claims was revived in some alternative medical circles by the 1987 book "The Cancer Cure That Worked", which claimed that Rife had succeeded in curing cancer, but that his work was suppressed by a powerful conspiracy headed by the AMA.
Rife claimed to have documented a "Mortal Oscillatory Rate" for various pathogenic organisms, and to be able to destroy the organisms by vibrating them at this particular rate. According to the San Diego Evening Tribune in 1938, Rife stopped short of claiming that he could cure cancer, but did argue that he could "devitalize disease organisms" in living tissue, "with certain exceptions".
- Real time display of LF/HF
- Enhanced ectopic beat elimination
- All data saved to files for offline analysis
- Improved stability
Ectopic beats are captured by Lagrangian interpolation of the data stream.
LF/HF is calculated by resampling the dataset at 4Hz them applying Welch's periodogram through a 256 point FFT using a 16 sample wide window and an 8 sample overlap.
The uncorrected raw R-R samples are saved in a file named "year-month-day-hour-minute-second-r2r.txt"
The HRV parameters calculated and displayed during operation are saved in a file named "year-month-day-hour-minute-second-sd1.txt"
The filenames are the time the program was started and are saved in the directory HRVpro/data.
Both files can be imported into Excel and the r2r file can be directly opened in Kubios.
Next steps: Plot LF/HF as skinny bars withing the SD1 plot
1. This app is for general interest only and SHOULD NOT be used for any clinical purpose.
2. CONSULT YOUR PHYSICIAN before undertaking any strenuous activity
3. This app requires a Polar Wearlink+ Transmitter With Bluetooth (Available from Amazon)
4. App was developed and tested on Samsung S3
5. Some users of the free version of the app have reported odd behavior such as failing to connect properly (with the display remaining at 'listening') and the app displaying improbably high values. Both of these conditions have been seen during development of the app and appear to be an Andriod related issue ( when the device gets itself in this state, 'Cardio Training' fails as well).
Recovery from this condition can be achieved by shutting the device down completely then restarting.
