ABSTRACT
BACKGROUND AND OBJECTIVES:
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common regular supraventricular tachycardias in both the general population and elderly patients. The aim of this study is to investigate the clinical and electrophysiologic characteristics and efficacy of radiofrequency catheter ablation (RFCA) for treating AVNRT in the elderly. SUBJECTS ANDMETHODS:
This study included 273 consecutive symptomatic AVNRT patients who underwent RFCA for the slow-pathway. The study population was divided into two groups group I patients were younger than 65 years (n=227, average age 44.6+/-12.9 years, male female=89 138) and group II patients were older than 65 years (n=46, average age 69.0+/-3.6, male female=9 37). We compared the baseline clinical, electrocardiographic and electrophysiologic characteristics and the outcomes of RFCA between the two groups.RESULTS:
The prevalence of a baseline prolonged PR interval (>200 ms) was not different between the 2 groups (1.8% vs. 6.5%, p>0.05). The baseline sinus cycle length, QT interval and AVNRT cycle length were significantly longer in group II than in group 1 (799.3+/-146.1 ms vs. 864.3+/-159.8 ms, 374.2+/-42.1 ms vs. 397.6+/-40.4 ms, 351.3+/-43.2 ms vs. 384.9+/-57.0 ms, respectively p or =second degree) was not different between the two groups (4.0% vs. 6.5%, p>0.05). One patient in group I required permanent pacemaker implantation.CONCLUSION:
RFCA in elderly patients is safe and effective as in younger patients. Therefore, performing RFCA for treating AVNRT should also be considered in the elderly patients.
