WebSep 9, 2015 · Ventricular demand appears as a single pacemaker spike followed by a typical QRS pattern that is representative of a ventricular repolarization. This pattern often is associated with atrial fibrillation. Dual chamber sequential AV pacing may be identified on an EKG as a pacemaker spike prior to the P wave and QRS complex. WebJan 28, 2024 · A pacemaker has two primary functions, pacing (an electrical stimulus for myocardial depolarization) and sensing (detecting intrinsic electrical activity and wave of depolarization). Different timing cycles are programmed in a pacemaker for …
