Basics on using ECG calipers.

I just use the Elite HRV app with my Polar H10. It records the RR interval and calculates the mean and moda of the RR interval. It also calculates the SDRR and the RMSSD from which the HRV is derived. You can also download the RR interval raw data for additional analysis.

Yes, there are many good apps out there. This is for practicing manual trace reading for the beginner.

Sir which book is it?

[@JCruiseII]

There are many ECG books out there. The system to read the tracing is the same regardless of which book you are using.
