ANATOMY

Detailed explanation-1: -The T wave on the ECG (T-ECG) represents repolarization of the ventricular myocardium. Its morphology and duration are commonly used to diagnose pathology and assess risk of life-threatening ventricular arrhythmias.

Detailed explanation-2: -T wave. T waves represent ventricular repolarization (atrial repolarization is obscured by the large QRS complex).

Detailed explanation-3: -Normal T-wave Etiology Ventricular repolarization is the process by which the ventricular myocytes return to their negative resting potential so they can depolarize again. While this phase of the cardiac cycle is rapid, an upright low amplitude broad hump following the QRS complex is seen in normal T wave morphology.

Detailed explanation-4: -The T wave on the electrocardiogram corresponds with ventricular repolarization (letter D). Other parts of the electrocardiogram also have the corresponding processes in the cardiac action potential. The P wave is due to atrial depolarization.

Detailed explanation-5: -The T wave on an ECG corresponds to ventricular repolarization. Atrial depolarization is represented by the P wave and ventricular depolarization by the QRS complex. The isoelectric or zero line between the P wave and the Q wave represents depolarization of the AV node, bundle branches, and Purkinje system.
