Long-term outcomes of atrial antitachycardia pacing to prevent progression to permanent atrial fibrillation in patients implanted with pacemakers.

ABSTRACT:

Background

A second-generation atrial antitachycardia pacing (ATP), reactive ATP (rATP), was effective in preventing progression to permanent atrial fibrillation (AF) in patients with sick sinus syndrome (SSS) over a 2-year follow-up period. However, its long-term results and efficacy in patients with atrioventricular block (AVB) remain uncertain.

Objective

This study aimed to evaluate the long-term efficacy of rATP in patients implanted with pacemakers owing to SSS and AVB.

Methods

The incidence of progression to permanent AF was compared between 2 groups of the 349 patients implanted with dual-chamber pacemakers (134 with rATP function [rATP group] and 215 without rATP [control group]).

Results

During the follow-up period (1906 ± 950 days), 57.5% of the patie
