摘要
应用动态心电图对６８例冠心病病人进行动态监测。结果显示，无症状心肌缺血发生率为８６．２７％，特别是冠心病合并糖尿病病人无症状心肌缺血发生率高达９４．６４％，无症状心肌缺血发作时平均心率为９１．３８±１７．９０ＢＰＭ，与症状性心肌缺血发作时的平均心率１０８．７５±１６．６２ＢＰＭ比较有显著差异（Ｐ＜０．００１）。此外，监测发现无症状心肌缺血发作频率多分布于６：００～１０：００时，占其总数的４５．９１％。
Ambulatory electrocardiography (AECG) can record myocardial electrical activities for a longer time than routine 12-lead ECG. Sixty-eight patients with coronary heart disease (CHD) underwent 24-hour AECG recordings.The result showed that the incidence of silent myocardial ischemia (SMI) in patients who accompanied with diabetes mellitus (DM) increased to 94.64%.The difference of the heart rates between the patients with SMI and those with symptomatic myocardial ischemia was significant.They were 91. 38 ±17. 90BPM and 108.75±16.62BPM,respectively(P<0. 001).We also found that SMI frequently occurred from 6 to 10 a. m.Our data suggest that occurrence of SMI is related not only to myocardial oxygen consumption,but also to neuroendocrine and other factors.
