The SelfLoops HRV application calculates and displays the heart rate variability.
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. For an intro to HRV see: http://en.wikipedia.org/wiki/Heart_rate_variability
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.
