The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
SA node What does the ECG wave tracing represent? Electrical activity in the heart What does the ORS complex represent in the ECG wave tracing? Ventricular depolarization Contraction of the atria results from which wave of depolarization on the ECG tracing? P wave Which part of the intrinsic conduction system delays impulse briefly before it moves on to the ventricles?
