Conclusion: Responses of HRV indices were more prominent during M-RSA in moderate to severe COPD. Moreover, greater lung function impairment was related to poorer heart rate dynamics.
Web9 jul. 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.
