Heart Rate Variability
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.
There are several metrics used in the scientific literature, we calculate: SDNN, RMSSD, pNN50, AVNN.
Bluetooth Low Energy or ANT+ heart rate monitorRequires a Bluetooth low energy heart rate monitor (Bluetooth Smart, Bluetooth 4.0). For example Polar H7,H6, Wahoo Blue or Tickr, Viiiiva. The Android version also supports ANT+ heart rate monitors (like Garmin and many others).
Store all your HRV dataThe application maintains an archive of recordered HRV values and it will show you the R-R and heart rate line charts
Export featureYou can upload your data on SelfLoops or export them by email, DropBox or Google Drive.
Make sure you are using a a Bluetooth Smart (Bluetooth 4.0, Bluetooth Low Energy) certified heart rate monitor.
Make sure that is not paired already with another application or device. Also, do not pair the heart rate monitor in the Settings of your device. The Bluetooth standard does not allow to have the heart rate monitor connected at the same time to multiple apps or devices.
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.
