WebJun 13, 2024 · In the above EKG strip, you see the R to R intervals are equal so we can say that this is a regular rhythm. If R-R intervals vary by less than 1.5 boxes, the rhythm is still considered a regular rhythm. We see that there are 7 R-waves. We multiply 7 x 10 and that equals 70 bpm (beats per minute). So the ECG heart rate in the above is 70 bpm. they enjoyed the summer in france duolingo
