Web17 Aug 2012 · Undersensing of PACs should be excluded and may require longer tracings or device interrogation. Figure 24. Wide QRS beat encountered during regular atrial pacing with short PR interval. This is most likely a premature ventricular contraction (PVC), fusing with the atrial paced, spontaneously conducted beat. Figure 25. WebModel 53401 is a battery-powered external single chamber pacemaker for temporary use. It provides four common pacing modes, including on-demand VVI/AAI (synchronous) and VOO/AOO (asynchronous), as well as burst functionality for managing atrial tachyarrhythmias.
