The QRS complex represents ventricular depolarization. The P wave represents the depolarization of the atria. The PR interval represents depolarization of the atria,atrioventricular node,bundle of His,bundle branches,and the Purkinje fibers. The Q wave is the first negative deflection following the P wave and should be narrow and short.
