In electrocardiography, the T wave represents the repolarization, or recovery, of the ventricles. This is the phase following the depolarization phase, during which the ventricles return to their resting state. The T wave is typically positive in most leads of the ECG, reflecting the electrical activity as the ventricles repolarize. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period, which is a critical time for the heart muscle to reset before the next contraction can occur. It's important to note that while a positive T wave is common, a negative T wave is normal in lead aVR due to its specific anatomical positioning and the direction of electrical forces it captures.
