Other Parts Discussed in Thread: AWR6843
We need to develop a vital monitoring system using AWR6843 AOP. We need to get Heart rate, Breath rate and Hear rate variability values from the system. Please tell me about the possibility to get heart rate variability values from the sensor output.
For your reference regarding Heart rate variability :
The mathematical formula to calculate heart rate variability (HRV) from heart rate value is:
RMSSD = sqrt(mean(abs(diff(RR_intervals))^2))
where:
RMSSD = root mean square of successive differences
RR_intervals = the time intervals between successive heartbeats
mean = the average
abs = the absolute value
diff = the difference between two values
To calculate RMSSD, you first need to calculate the difference between each successive RR interval. Then, you square each of these differences and take the average. Finally, you take the square root of the average to get RMSSD.
