Step 1
An ECG (electrocardiogram) tracing records the electrical activity of the entire heart over time, as detected on the body surface. It reflects the summed electrical signals from many cardiac cells during a single cardiac cycle, including atrial depolarization (P Show more…

Explain the ECG, what do the waves describe and related with the movement of the the action potential.

Given below is an ECG. Use this to • Draw an action potential of cardiac muscle and explain how ECG correlates with the action potential • Compare and contrast Action potential of a cardiac muscle with that of a neuron

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?
