目的:动态心电图对心肌缺血监测分析的意义。方法:对288例冠心病患者的动态心电图检查进行回顾性分析,从监测结果中选出记录到心肌缺血的153例,共1599阵次ST段压低进行了分组和统计学处理。结果:无痛性心肌缺血(SMI)130例(65%),伴典型心绞痛者仅17例(11%),心肌缺血发作时快频率依赖者99例(64%),昼夜发作规律为0:00-9:00发生率最高,缺血后O-TC无明显差异。结论:动态心电图对心肌缺血的监测具有重要意义。
Objective: The significance of dynamic electrocardiogram in myocardial ischemia monitoring and analysis. Methods: The dynamic electrocardiogram of 288 patients with coronary heart disease were retrospectively analyzed. From the monitoring results, 153 patients with myocardial ischemia were selected and 1599 ST-segment depression were grouped and statistically analyzed. Results: Painless myocardial ischemia (SMI) was found in 130 patients (65%), only 17 patients (11%) with typical angina pectoris, 99 patients (64%) with fast frequency dependence during myocardial ischemia, 0: 00-9: 00 the highest incidence of ischemic O-TC no significant difference. Conclusion: Holter monitoring of myocardial ischemia is of great significance.
