心肌缺血阈(MIT)是指冠心病者在动态心电图(DCG)检查中发生暂时性心肌缺血时的心率水平,通过检测最高心肌缺血阈(HMIT)、最低心肌缺血阈(LMIT)及心肌缺血变异性可以发现冠心病者心肌缺血阈的变化规律,从而评价冠心病者各种疗法的疗效及指导患者运动量。1资料与方法1·1对象病例
Myocardial ischemia threshold (MIT) refers to the heart rate of patients with coronary heart disease during transient electrocardiogram (DCG) examination of myocardial ischemia, by detecting the highest myocardial ischemia threshold (HMIT), minimum myocardial ischemia threshold (LMIT) And myocardial ischemia variability can be found in patients with coronary heart disease myocardial ischemia threshold changes in order to evaluate the efficacy of various therapies in patients with coronary heart disease and guide patients exercise. 1 Materials and Methods 1.1 object cases
