In electrocardiography, the T wave represents the repolarization, or recovery, of the ventricles following their depolarization. This wave is typically the third distinct phase in a typical ECG cycle, coming after the P wave (which represents atrial depolarization) and the QRS complex (which indicates ventricular depolarization). The T wave's elevation, morphology, and duration can provide important diagnostic information about the heart's electrical activity and overall health.
The interval from the beginning of the QRS complex to the apex of the T wave is known as the absolute refractory period. During this time, the ventricles are in a state where they are not responsive to any electrical stimulus, which is crucial for preventing the ventricles from contracting again before they have fully relaxed. This period ensures that the heart has a proper and efficient contraction and relaxation cycle.
