摘要
目的 探讨用心肌缺血负荷值评价不同部位心肌梗死后心肌缺血的临床价值。方法 采用美国Mar quette 2 4h三通道磁带记录盒连续动态心电监测 ,对 36 8例心肌梗死后患者进行ST段分析。结果 10 8例心肌梗死后Holter检出心肌缺血 ,检出率 2 9 3 % ;10 8例中共 12 2 6次心肌缺血 ,其中无症状心肌缺血占 98 85 % ;不同部位心肌梗死的心肌缺血负荷值无显著差异 ;昼夜心肌缺血负荷值无显著差异。结论 心肌缺血负荷值是分析比较ST段改变的一个准确的量化指标 ,能有效的检出不同部位心肌梗死后心肌缺血的程度 ,为临床对心肌梗死后心肌缺血的疗效观察提供有效的量化指标。
Objective To implore clinical values of myocardial ischemia loading worth (TIB) used to evaluate myccardial ischemia after different wall myocardial infarction were continuously monitored by Marquette 24 hr three channel magnetic tape recorder U.S.A. ST segments were analysed in 368 patients. Results 108 patients had myocardial ischemia. The detectable rate of myocardial ischemia was 29.3 percent after myocardial infarctions. Asymptomatic myocardial ischemias were accounted for 98.85 percent in 1226 myocardial ischemias. There was no significant difference in TIB of different wall myocard ial infarction so in day and night TIB. Conclusion TIB is an accurate quantitative marker to analyze ST segments change. It can effectively compare degree of myocardial ischemia after myocardial infarction and provide effective quantitative marker for detection and observation of treating effectiveness of myocardial ischemia after myocardial infarction in clinic.
