目的探讨老年人心电图的特点及临床意义。方法对1098例离退休老年人行常规12导联心电图描记。结果异常心电图的检出率为58.0%(637/1098),在异常心电图中,最多的为缺血型ST-T改变261例(23.8%),其次为传导阻滞122例(11.1%);以右束支传导阻滞为主,其次是左前分支传导阻滞、Ⅰ度房室传导阻滞、完全性左束支传导阻滞。在心律失常中,以室性期前收缩和心房纤颤发生率最高,分别为40例(3.6%)和28例(2.6%)。结论心电图异常检出率随年龄增长而递增,提示对老年人群应定期进行心电图检查。
Objective To investigate the characteristics and clinical significance of electrocardiogram in the elderly. Methods A total of 1098 retired elderly patients underwent conventional 12-lead electrocardiography. RESULTS: The positive rate of abnormal electrocardiogram was 58.0% (637/1098). Among the abnormal ECGs, the maximum number of ischemic ST - T was 261 (23.8%), followed by conduction block (122.1%). Right bundle branch block, followed by left anterior branch block, Ⅰ degree atrioventricular block, complete left bundle branch block. In arrhythmia, ventricular premature contractions and the highest incidence of atrial fibrillation were 40 (3.6%) and 28 (2.6%), respectively. Conclusions The detection rate of ECG anomaly increases with age, suggesting that electrocardiogram should be performed on the elderly regularly.
