WebJun 24, 2010 · Pacemaker. A pacemaker is indicated when electrical impulse conduction or formation is dangerously disturbed. The pacemaker rhythm can easily be recognized on the ECG. It shows pacemaker spikes: vertical signals that represent the electrical activity of the pacemaker. Usually these spikes are more visible in unipolar than in bipolar pacing. WebDual Chamber Pacemaker (ECG) An endocardial dual chamber pacemaker with leads to the right atrium and the morphologic LV was implanted and set to pace in dual chamber (DDD) mode at 60–150bpm.
