Question: 1 / 400

True or False: The T wave of the EKG represents ventricular depolarization.

True

False

The statement is false because the T wave of the EKG represents ventricular repolarization, not depolarization. During the cardiac cycle, ventricular depolarization is represented by the QRS complex, which includes the electrical activity leading to heart muscle contraction. Following this contraction, the heart muscle cells repolarize, which is reflected in the T wave. Understanding this distinction is crucial for interpreting EKG readings correctly. The QRS complex displays the initiation of ventricular contraction, while the T wave indicates the return of the heart muscle to its resting state after contraction. Thus, option B accurately identifies the nature of the T wave, reinforcing the correct understanding of EKG components and their significance in the cardiac cycle.
