目的分析老年无症状频发室性心律失常的临床特点。方法选择2012年2月—2015年2月采用24h动态心电图监测,且提示具有无症状频发性室性心律失常100例老年患者,随机分为观察组(经胺碘酮治疗)和对照组(不接受治疗),比较两组临床安全性。结果 100例室性心律失常患者均具有频发室性早搏,维持在9000/d~18000/d,均无临床症状。其中17例为短暂性阵发室性心动过速,13例ST-T异常,26例并发短阵房颤。两组患者随访3个月中,观察组不良症状发生率为12%,对照组为34.0%;观察组安全率为88.0%,显著高于对照组的66.0%,具有统计学差异(P<0.05)。结论老年无症状频发室性心律失常经24h动态心电图监测,可及早发现病症,采用胺碘酮治疗,可显著提高临床安全性。
Objective To analyze the clinical features of asymptomatic and frequent ventricular arrhythmias in the elderly. Methods From February 2012 to February 2015, 100 elderly patients with asymptomatic ventricular arrhythmia were monitored by 24h Holter monitoring and were randomly divided into observation group (treated with amiodarone) and control group (treated with amiodarone) Not receiving treatment), comparing the clinical safety of the two groups. Results All 100 patients with ventricular arrhythmia had frequent premature ventricular contractions, and maintained at 9000 / d ~ 18000 / d, no clinical symptoms. Among them, 17 cases had transient paroxysmal ventricular tachycardia, 13 cases had abnormal ST-T, and 26 cases had atrial fibrillation. The incidence of adverse symptoms was 12% in the observation group and 34.0% in the control group in the three months follow-up. The safety of the observation group was 88.0%, which was significantly higher than that of the control group (66.0%, P <0.05 ). Conclusion Asymptomatic and frequent ventricular arrhythmia in elderly patients monitored by dynamic electrocardiogram 24h, early detection of illness, the use of amiodarone treatment, can significantly improve clinical safety.
