WebApr 14, 2024 · The normal T wave is in the same direction as the preceding QRS complex. In leads V 1 and V 2, the T wave may be positive in spite of a dominantly negative QRS complex. Repolarization of the ventricular cells causes a flow of ions in a direction opposite to that of depolarization. It is, therefore, expected that direction of the T wave should ... WebIn addition to the P wave, QRS complex, and T wave, other features of ECG signals can also provide important information about cardiac function. For example, the PR interval represents the time between the start of the P wave and the start of the QRS complex and can indicate abnormalities in atrioventricular conduction.
