Pythonic heart rate

Using python and the great matplotlib library, I have made a little app that measures the hart rate and computes various heart rate variability parameters (such as rMSSD, pNN50, LF, HF). On the hardware side, the pulse sensor connected to an Arduino Uno microcontroller is used. Parts of the code are based on other open source libraries. […]

Heart rate variability

Heart Rate Variability (HRV) describes the variation in the time interval between heartbeats and it is often calculated based on RR intervals (i.e. the interval between two successive R-peaks in the ECG wave). HRV is relevant for clinical monitoring of patients, in psychophysiology, as well as in sports. There are several approaches to measure HRV “at home”, such as: […]
