Signal Quality: Raw vs Corrected R-R Intervals
“Raw” RR intervals are the RR intervals that are received directly from the HR monitor and have not been cleaned or corrected for artifacts such as ectopic beats or signal noise.
“Corrected” RR intervals are the RR intervals after our algorithms have of detected and corrected artifacts such as ectopic beats or signal noise to provide a more valid signal for HRV analysis.
By comparing the “Raw” and “Corrected” RR intervals, you can see where artifacts existed and were corrected to better understand the quality of you measurement and validity of the results.
The mobile app and web dashboard do this for you automatically. This is what it looks like in both places:
