本文报告221例心肌梗塞后3周运动试验的研究结果。患者平均年龄57岁,40例女性。按 Bruce 方案进行症状限制性运动试验。运动时连续监测心电图和血压,并规定任何导联 ST 段压低≥1mm 为试验阳性。极量运动时收缩压增高不超过静息收缩压的10%为运动血压反应不良。其中123例运动时服用β-阻滞剂.结果 89例(40%)有显著 ST 段压低(阳性试验组),其中72例行冠状动脉造影术,诊断为单支血管病变24例,双支15例,3支33例。132例无 ST 段压低
This article reports 221 cases of myocardial infarction after 3 weeks of exercise test results. The average age of patients was 57 years old, 40 women. Symptomatic restrictive exercise test was performed according to the Bruce protocol. Exercise continuous monitoring of ECG and blood pressure, and the provisions of any lead ST segment depression ≥ 1mm positive test. Excess systolic blood pressure during exercise does not exceed 10% of resting systolic blood pressure for adverse exercise reactions. Among them, 123 patients took β-blocker during exercise.Results 89 (40%) patients had significant ST-segment depression (positive test group), of which 72 underwent coronary angiography, diagnosed as single vessel disease in 24 cases, 15 cases, 3 cases 33 cases. 132 cases without ST-segment depression
