Q. ECG depicts the depolarisation and repolarisation processes during the cardiac cycle. In the ECG of a normal healthy individual one of the following waves is not represented

Solution:

An electrocardiogram or an ECGuses an instrument to record the electrical activities of the heart. It records the electrical impulses, more specifically the change in the electrical impulses of the heart, and plots it on a graph. The readings of an individual's ECG are compared with a standard ECG to evaluate the working of the heart and checking it for any abnormalities or diseases. Different waves in ECG represent different events in the cardiac cycle but none of them depicts the repolarization of the atria.
So, the correct answer is 'Repolarization of atria.'
