Pacing induced tachycardia model

WebAT induced in this CHF model after 3 to 4 weeks of rapid ventricular pacing has an activation pattern consistent with a focal origin. Sites of earliest activation are distributed predominately along the crista terminalis and within or near the pulmonary veins. WebJun 4, 2024 · Rapid ventricular pacing. There is a rapid ventricular-paced rhythm (120 bpm) with no evidence of preceding atrial activity (except for the first complex). The differential diagnosis of this rhythm would include: Pacemaker-mediated tachycardia (with retrograde P waves buried in the QRS complexes /T waves). Sensor-induced tachycardia.
