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.
The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram (EKG or ECG) .It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the human heart.ny abnormality of conduction takes longer and causes widened QRS complexes. In bundle branch block, there can be an abnormal second upward deflection within the QRS complex, in this case such a second upward deflection is referred to as R' (pronounced R prime). This would be described as an RSR' pattern.
