What is depolarization in ECG?

Atrial and ventricular depolarization and repolarization are represented on the ECG as a series of waves: the P wave followed by the QRS complex and the T wave. The P Wave. The first deflection is the P wave associated with right and left atrial depolarization.

What is the depolarization and repolarization?

When the electrical system if the heart stimulates a myocardial cell, dePOLARization occurs, resulting in the contraction of the stimulated heart muscle. RePOLARization is the process of reaching the resting state before they can electrically simulated again.
