antitachy
Antitachycardia pacing (ATP) is a pacing therapy delivered by implantable devices such as implantable cardioverter-defibrillators (ICDs) and some pacemakers to terminate tachyarrhythmias, most commonly monomorphic ventricular tachycardia. Unlike shocks, ATP uses a sequence of rapid paced impulses designed to interrupt the reentrant circuit causing the tachycardia, potentially restoring a normal rhythm with less patient discomfort and lower energy use.
ATP is delivered after tachycardia is detected and is typically applied in designated therapy zones. The pacing
Effectiveness varies: ATP terminates many episodes of stable, monomorphic VT and can significantly reduce the number
In practice, ATP is part of a broader strategy for arrhythmia management, often used in conjunction with
