ECG & HEART SOUNDS 1. 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? 2. In the Analysis, you calculated heart rate averaged over 15 seconds and instantaneous heart rates. Explain any differences between these values. 3. Are the amplitudes and durations of the P wave and QRS complex related to the size and thickness of the atria and ventricles?
