Temporary transvenous pacing or an implanted cardiac pacemakerAn electronic pulse generator that stimulates depolarization of the atria and/or the ventricles. 1. Six Second ECG Guidebook (2012), T Barill, p. 201 with a lead in an atriaRight and left atria (1/3 volume and muscle mass of the ventricles) pump blood to the ventricles. Chambers and Layers of the Heart 1. Six Second ECG Guidebook (2012), T Barill, p. 190 (typically right atria) that initiates a depolarizing wave (pacer spikeThe telling sign that the rhythm is a paced rhythm; since the pacemaker spike is vertical, virtually no time was spent – this suggests strongly that the spike was initiated artificially and not organically (within the heart); note that a... followed immediately by a p waveA wave generated from the depolarization of the atria; the P wave is upright when originating from the SA node.
