The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
The first part of the normal sinus P Wave represents depolarization of the right atrium; the second part represents depolarization of the left atrium. During the P Wave, the electrical impulses progress from the SA node through the intermodal atrial conduction tracts and most of the AV node.
