众所周知,心绞痛患者无症状时和完全无症状者可发生一过性心肌缺血,称为“隐性心肌缺血”。在激发试验时出现此种情况亦提示预后不良,如经前瞻性研究证实,症状性和无症状性缺血的检出、定量计算和定性描述将对冠心病患者的治疗有重要意义。动态心电图监测院外发生缺血性ST段改变是日常
As we all know, asymptomatic patients with angina and complete asymptomatic transient myocardial ischemia can occur, known as “hidden myocardial ischemia.” In the excitation test when the situation also prompted a poor prognosis, as confirmed by prospective studies, the detection of symptomatic and asymptomatic ischemia, quantitative calculation and qualitative description of coronary heart disease patients with treatment of great significance. Holter monitoring of ischemic ST-segment changes outside the hospital is routine
