Yes since your heart rate fluctuates based upon your activity level. Resting heart rate varies greatly from your active heart rate. The P wave and the QRS complex represent depolarization of the atrial and ventricular muscle respectively. Why does the QRS complex have the larger amplitude? The QRS complex correlates with the action needed to push blood back out away from the heart that requires higher pressure. Heart rate was calculated based upon the peak-to-peak interval of the R waves.
It is measured from the beginning of the QRS complex to the end of the T wave. At a heart rate of 70 beats per minute it is usually about 0.35 seconds in duration, but the duration of the QT interval is very heart rate dependent. The lower the heart rate is, the longer the QT interval.or example if there is 0.6 seconds between beats, and there are 60 seconds per minute, then the heart rate would be 100 beats per minute [(60 sec/minute / (0.6 sec/beat)]. The RR interval is measured from the peak of one QRS complex (R wave) to the peak of the next QRS complex.
