Abstract

PURPOSE:  To investigate in patients with automatic implantable cardioverter-defibrillators (AICDs) mortality at long-term follow-up of patients with dual-chamber rate responsive pacing at 70/minute (DDDR-70) versus ventricular backup pacing at 40/minute (VVI-40).

METHODS:  We performed a retrospective study to determine all-cause mortality in all patients at a university hospital who had AICDs without indications for antibradycardia pacing. Of 535 patients, mean age 70 years, 271 patients had backup ventricular pacing with a VVI-40, and 264 patients had dual-chamber rate responsive pacing with a DDDR-70.

RESULTS:  At 3.7-year mean follow-up, all-cause mortality was 19% (50 of 264 patients) in patients with DDDR-70 pacing versus 11% (29 of 271 patients) with VVI-40 pacing (p<0.01).

CONCLUSION:  Because of the increased mortality, increased costs, and complexity for dual-chamber rate responsive pacing in patients with AICDs, concomitant DDDR pacing at a rate of 70/minute in patients without an indication for antibradycardia pacing is not warranted.

CLINICAL IMPLICATIONS:  In patients with AICDs, concomitant DDDR pacing at a rate of 70/minute in patients without an indication for antibradycardia pacing is not warranted.
