Initiation of ventricular tachycardia by interruption of pacemaker-mediated tachycardia in a patient with a dual-chamber implantable cardioverter defibrillator.
A 74-year-old man with a dual-chamber implantable cardioverter defibrillator implanted 3 years before experienced multiple ventricular tachycardias (VTs). All episodes were initiated by pacemaker-mediated tachycardia (PMT) that was either stopped by atrial undersensing or the tachycardia termination algorithm of the device. After the termination of PMT, two rapid ventricular paced beats, the fi...
متن کاملReversion of ventricular tachycardia by pacemaker stimulation.
Reversion of ventricular tachycardia to either sinus rhythm or atrialfibrillation has been achieved in a group ofpatients by rapid ventricular pacing. The standard technique involved pacing at a rate slightly in excess of the existing tachycardia until ventricular capture was achieved. Cessation ofpacing after afew seconds was usuallyfollowed by a supraventricular rhythm, though pacing at a low...
متن کاملSelective atrial sensing in dual chamber pacemakers eliminates endless loop tachycardia.
With the introduction of dual chamber pacemakers that have multiple atrial amplitude sensing values, selective P wave sensing is possible. Five consecutive patients were studied who had 1) retrograde atrioventricular conduction, 2) anterograde atrial signals that were at least 1.4 times larger than their corresponding retrograde atrial signals, and 3) dual chamber pulse generators that are capa...
متن کاملTachycardia-induced unexpected pacemaker behaviour
At the beginning of the recording, atrial tachycardia (AT) can be observed with 1:1 conduction at ventricular rate 140 bpm (upper track). At the spontaneous termination of the tachycardia, atrial-ventricular pacing at 45 bpm (lower rate) and after two cycles atrialventricular pacing at 100 beats/min (upper track) can be observed. The rate drop response was activated: drop size 25 ppm, drop rate...
متن کاملVentricular fibrillation triggered by a pacemaker-mediated tachycardia protection algorithm.
A 27-year-old man with complex congenital heart disease (double discordance and complete congenital atrioventricular block) previously implanted with a single-chamber pacemaker was successfully resuscitated from sudden death due to ventricular fibrillation (VF). Echocardiography showed a moderately dilated right systemic ventricle with systolic dysfunction (right ventricular ejection fraction 3...
