右束支传导阻滞患者,用次极量运动试验检出冠心病的敏感性尚不清楚。作者对30例右束支传导阻滞患者,做了次极量平板运动试验和选择性冠状动脉造影对照观察。方法30例患者平均年龄54(30～69)岁,其中男27例,女3例。因胸痛27例,因臂痛1例,因有1次心肌梗死病史为估计运动的耐受性的3例及因不好解释的呼吸短促1例而做次极量运动试验。用Bruce方案另加一个○级(无倾斜,1.7M/小时),12导联心电图记录:运动前病人卧位、立位,运动中每3分钟和运动结束后10分钟内每2分钟卧位记录1次。用
Right bundle branch block patients with submaximal exercise test to detect the sensitivity of coronary heart disease is not yet clear. The author of 30 cases of right bundle branch block patients, submaximal treadmill exercise test and selective coronary angiography control. Methods The average age of 30 patients was 54 (30-69) years old, including 27 males and 3 females. 27 cases of chest pain, 1 case of arm pain, 3 cases of history of myocardial infarction to estimate exercise tolerance, and 1 case of shortness of breath due to poor interpretation. With Bruce program plus a ○ (no tilt, 1.7M / hour), 12-lead ECG records: Pre-exercise patient supine, standing, exercise every 3 minutes and 10 minutes after the end of exercise every 2 minutes Record 1 time. use
