Overdrive atrial pacing
WebAtrial overdrive pacing during SVT • A young female with palpitations and paroxysmal supraventricular tachycardia (SVT) undergoes EP study. SVT is induced. Response to atrial overdrive pacing during SVT is shown (Figure 1). • Which (one or more) of the mechanisms can be consistent with the response to atrial overdrive pacing? WebOverdrive atrial pacing is started at a rate 5% to 10% faster than the flutter atrial rate and is maintained for 15 or more seconds. Overdrive pacing is repeated at incrementally faster rates until NSR is restored as AF develops. When overdrive atrial pacing alone fails, high-frequency (50-Hz) burst atrial pacing or overdrive pacing with atrial ...

WebAug 21, 2003 · The dynamic atrial overdrive algorithm, known as the AF Suppression TM algorithm (St Jude Medical, Sylmar, CA), is used in combination with a dual-chamber pacing device to suppress AF. Compared ... WebAim: post mode switch overdrive pacing (PMOP) can be added to the mode switch function to pace the atria rapidly after the cessation of an episode of atrial tachyarrhythmia. The emergence of a slow heart rate after the end of an arrhythmia is associated with an increased risk of very early recurrence.
WebJan 1, 2003 · Atrial overdrive In patients with conventional pacing with a DDDR pacemaker, it is simple to just increase the backup rate to suppress AF. Ward and … WebOverdrive atrial pacing can terminate AFL in about 82% (range 55% to 100%), and is especially effective in patients receiving antiarrhythmic medications. Overdrive pacing is …
WebFeb 25, 2008 · Overdrive atrial and ventricular pacing or premature extrastimuli were used to induce sustained SVT. Isoproterenol was infused at a rate of 2–4 mcg/min if the tachycardia was non-sustained or non-inducible at baseline. Once tachycardia was induced, standard criteria were used to establish the diagnosis of AT, AVNRT, or AVRT. WebRight atrial overdrive pacing (ODP) wire was introduced through femoral vein and allowed to override the tachycardia with 2:1 A:V block and HR of 160 bpm. ODP was continued …
WebAtrial overdrive pacing paces the atrium at a rate higher than the patient's intrinsic rate, then gradually decreases the pacing rate. Because the atrial rate can reach well over …
