WebThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers … WebP wave Small upwards deflection. Represents atrial depolarization. Action potential spreads from the SA node through contractile fibers in both atria QRS complex Begins as a downward deflection, continues as a large, upright, triangular wave, and ends as a downward wave. Represents rapid ventricular depolarization.

WebECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal.
