Atrial adaptive rate pacing in sick sinus syndrome: effects on exercise capacity and arrhythmias.
OBJECTIVE To test the hypotheses that adaptive rate atrial (AAIR) pacing: significantly increases maximal exercise capacity, and results in significant suppression of supraventricular and ventricular arrhythmia compared with fixed rate atrial (AAI) pacing. DESIGN Prospective, randomised, single blind, crossover study with maximal treadmill exercise testing and 24 hour ambulatory electrocardio...
متن کاملWho Needs Physiologic Pacing and Why?
Various pacing technologies have been developed during the past 50 years since the first pacemaker was implanted in 1958. Dual-chamber pacing, rate responsiveness, programmable and rate-responsive atrioventricular (AV) intervals, alternative-site pa0cing, and new multichamber pacing devices are all attempts to mimic normal cardiac physiology as much as feasible. The categories of alternative-si...
متن کامل[Clinical safety and efficacy of single-chamber atrial pacing in sick sinus syndrome: long-term follow-up].
INTRODUCTION AND OBJECTIVES Although atrial pacing is a more physiological mode of stimulation in sinus node dysfunction, the pacing modes most often are used DDD and VVI. The aim of our study was to demonstrate that AAI/AAIR pacing is effective and safe by analyzing the complications and mortality of this pacing mode in a long-term follow-up study. PATIENTS AND METHOD Between 1982 and 2000 d...
متن کاملRegional myocardial blood flow in patients with sick sinus syndrome randomized to long-term single chamber atrial or dual chamber pacing--effect of pacing mode and rate.
OBJECTIVES This study aimed to evaluate regional myocardial blood flow (MBF) and global left ventricular ejection fraction (LVEF) during chronic pacing in patients with sick sinus syndrome (SSS) randomized to either single chamber atrial (AAI) or dual chamber (DDD) pacing. BACKGROUND Experimental studies indicate that chronic pacing in the right ventricular apex changes regional MBF, thereby ...
متن کاملIncreased AAI mode pacing threshold after termination of atrial fibrillation by acute administration of disopyramide phosphate.
AIMS We studied changes in atrial pacing threshold after termination of atrial fibrillation (AF) by acute administration of disopyramide phosphate (DP) to elucidate the suitable setting for atrial pacing output before AF termination. METHODS AND RESULTS Four patients with sick sinus syndrome implanted with AAI mode pacemakers were examined. Disopyramide phosphate (2 mg/kg body weight) was inj...
