I have 10 minute ECG data saved in CSV file format (13900 data samples corresponds to 10 minute recording). My sampling frequency is 139HZ. I found the distance between RR peaks (RR interval) in terms of data samples between two peaks. I need to find the RR Interval in seconds. So how I will convert the RR distance in terms of data samples to seconds. I will be grateful if someone can help me to solve this issue.

在 MATLAB Online 中打开

The obvious solution would be:

rrInSec = rrInSamples / samplingRateInHz
