In an electrocardiograph, (ECG) T wave represents
Correct answer: A. Ventricular repolarization
- A. Ventricular repolarization
- B. Ventricular depolarization
- C. Atrial repolarization
- D. Atrial depolarization
Explanation
The T wave in an ECG (electrocardiogram) represents ventricular repolarization, indicating the recovery of the ventricles before the next contraction.

About Cardiac Cycle and Heartbeat
The cardiac cycle describes atrial systole, ventricular systole and diastole, including pressure changes, blood movement and the opening or closing of heart valves. It also covers the conduction pathway from the sinoatrial node through the atrioventricular node, bundle of His and Purkinje fibres, and relates these events to heartbeat sounds.
