The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
P wave a positive deflection in the normal surface electrocardiogram produced by the wave of excitation passing over the atria; it represents atrial depolarization, an intrinsic atrial event. papillary wave (percussion wave) the chief ascending portion of the tracing of a sphygmograph.
