SpletIn a regular rhythm ECG, the heart rate may be derived from counting the number of large and small squares between two QRS complexes and examining the RR interval distance. This method has two steps: Step 1. RR duration = RR interval in mm* / 25 (or 50 if paper speed is of 50mm/s) Step 2. Heart rate in bpm = 60 / RR duration.
