WebHeart Rate Variability Heart rate variability (HRV) is the variation in time between consecutive heartbeats. It is a measure of the beat-to-beat changes in heart rate, which reflects the influence of the autonomic nervous system on the heart. HRV is typically measured by analyzing the electrocardiogram (ECG) signal, wh Web9 de jul. de 2014 · You cannot calculate the HRV from the heart rate - your need to use RR intervals. You need to check the data returned by your sensor to see if bit 4 of the flag byte is set - this indicates the presence of RR data. You can then read the RR data into an array, converting the 16 bit sample data into NSNumber s .
