WebThe ECG trace reflects the net electrical activity at a given moment. Consequently, activity in one direction is masked if there is more activity, eg, by a larger mass, in the other direction. For example, the left ventricle muscle mass is much greater than the right, and therefore its depolarization accounts for the direction of the biggest wave.

The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short refractory period after being subjected to an action potential (of the order of 1 ms). This can lead to sustained or tetanic contraction. In the heart, contractions must be spaced to maintain a rhythm. Unlike in muscle, repolarization occurs at a slow rate (100 ms). This prevents the heart from undergoing sustained contractions becaus… WebJan 17, 2024 · The T Wave indicates ventricular repolarization, in which the ventricles relax following depolarization and contraction.
