Question

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.

Options

• Depolarisation of atria

• Repolarisation of atria

• Depolarisation of ventricles

• Repolarisation of ventricles

Answer 1

Repolarisation of atria

Explanation:

During the cardiac cycle, the ECG illustrates the depolarization and repolarization processes. Repolarization of the atria is not seen in the ECG of a typical healthy person.
