Abstract

BACKGROUND

The aim of this study was to correlate early atrial fibrillation (AF) relapses with heart rate variability (HRV) parameters immediately recorded after electrical cardioversion (EC) of persistent AF.

METHODS AND RESULTS

We performed the spectral analysis of short-term HRV 30 min after EC in 25 patients with persistent AF. The numbers of patients who maintained sinus rhythm at 48 h, 7, and 30 days were 22, 16, and 14, respectively. A very low low frequency/high frequency ratio (0.93+/-0.08 vs. 1.89+/-1.30; p<0.003) significantly identified patients with AF recurrence at 48 h in comparison to patients without AF recurrence. On the contrary, HRV parameters did not identify patients with AF recurrence at 7 or 30 days.

CONCLUSIONS

AF relapsed within the first 48 h more frequently in patients who presented a predominant vagal tone immediately after the restoration of sinus rhythm.

摘要

背景

本研究旨在将持续性房颤电复律（EC）后立即记录的心率变异性（HRV）参数与早期房颤复发相关联。

方法与结果

我们对25例持续性房颤患者电复律后30分钟的短期HRV进行了频谱分析。在48小时、7天和30天时维持窦性心律的患者人数分别为22例、16例和14例。与无房颤复发的患者相比，极低的低频/高频比值（0.93±0.08对1.89±1.30；p<0.003）能显著识别出48小时内房颤复发的患者。相反，HRV参数无法识别出7天或30天时房颤复发的患者。
