Do Current Dual Chamber Cardioverter Defibrillators Have Advantages Over Conventional Single Chamber Cardioverter Defibrillators in Reducing Inappropriate Therapies? A Randomized, Prospective Study

Abstract

We conclude that the implanted DDD-ICD and conventional VVI-ICD are equally safe and effective for therapy of life-threatening ventricular tachyarrhythmias. Although DDD-ICDs allow better rhythm classification, the applied detection algorithms do not offer benefits in avoiding inappropriate therapies during supraventricular tachyarrhythmias.
