In ECG, P – wave represents A) Ventricular repolarization B) Ventricular depolarization C) Atrial depolarisation D) Atrial repolarization

Correct option:(C)Atrial depolarisation

Solution:

An ECG is a test to check the electrical activity of the heart.
ECG measures the atrial and ventricular depolarization and repolarization in the form of waves.
Comprises of three waves, P wave, QRS complex and T wave.
P wave in ECG represents atrial depolarization.
QRS complex represents ventricular depolarization.
T wave represents ventricular repolarization.
