本文报告22名健康老年人和20例老年心脏病患者24小时动态心电图监护记录结果。22名健康人中21名(占95.45%)有心律失常发生,其中以窦性心动过缓、室性早搏和房性早搏最多见(发生率分別为72.7%、63.6%和54.5%)。20例患者均有心律失常发生。健康组严重室性心律失常的发生率显著低于病人组。本文支持正常或无症状老年人心律失常相当常见的观点。 This article reports the results of 24-hour Holter monitoring records for 22 healthy elderly and 20 elderly patients with heart disease. Among 22 healthy persons, 21 (95.45%) had arrhythmia. Among them, sinus bradycardia, premature ventricular contractions and atrial premature beats were the most common (72.7%, 63.6% and 54.5% respectively). Twenty patients had arrhythmia. The incidence of severe ventricular arrhythmias in the healthy group was significantly lower than in the patient group. This article supports a fairly common view of arrhythmias in normal or asymptomatic seniors.
