Wave, Complexes and Intervals P wave The P waves represent the electrical impulse starting in the SA node and spreading through the Atria. Therefore the P wave represents atrial depolarization. Always in front of the QRS The QRS complex represents ventricular depolarization. The Q wave The first negative deflection after the P wave The R wave The R wave is the first positive deflection after the P wave The S wave The first negative deflection after the R wave The T wave It represents ventricular repolarization (when the cells regain a negative charge; also called the resting state) The U wave Thought to represent repolarization of the purkinje fibers; although
