摘　　要：应用三通道动态心电图（ＤＣＧ）对３００例老年心绞痛患者进行２４ｈ监测，发现无症状性心肌缺血（ＳＭＩ）１２７３次，分析结果表明：①ＳＭＩ是老年心绞痛患者心肌缺血的重要组成部分，３００例中有２４４例发生ＳＭＩ，占总例数的８１．３％；ＳＭＩ１２７３次占发生心肌缺血总次数的７８．５％；②ＳＭＩ的发生８２．１％与日常活动有关，并且有明显的昼夜分布规律，以上午６～１２时为发生高峰；③心肌缺血可诱发心律失常，心律失常亦可诱发或加重心肌缺血。The characteristics of silent myocardial ischemia(SMI)have been studied in300 patients with angina pectoris in the aged by three chennal Dynamic electrocardiographicmonitoring. The results have been shown:①SMI was an important part of myocardial is-chemia with angina pectoris in the aged.Among the 300 patients SMI occured in 244 (it ac-counted 81.3%of total patients).1273 episodes of ischemia(1662).②82%SMI was con-cerned with dialy actions. Meanwhile there is obvious day and night regularity. The frequencyof episodes of SMI peaked in the morning between 6 AM and 12 N.③SMI could induced ar-rhythmia, and it could been taken by arrhythmia.
