本文对90名男性病人进行踏车运动试验、平板运动试验、异丙基肾上腺素滴注试验、多巴胺滴注试验及心房调搏试验,最后再作冠状动脉造影,以比较这五种负荷试验的诊断价值。患者均无并发症,凡有静息时心电图异常、瓣膜病、心肌病、高血压性心脏病,以及不稳定型心绞痛者均予除外。试验前两周内均未用过洋地黄、心得安、利尿剂等药物。方法:踏车试验的负荷量由10瓦起始,按每分钟10瓦递增,直至心率达最大心率的85％为止。平板试验采用Bruce分级法。异丙基肾上腺素滴注由1微克/分起始,每三分钟增加1微克/分,直至心率达130次/分。多巴胺滴注由200微克/分起
In this paper, 90 male patients treadmill exercise test, treadmill exercise test, isoproterenol infusion test, dopamine infusion test and atrial pacing test, and finally for coronary angiography to compare the five load test Diagnostic value. Patients without complications, where resting ECG abnormalities, valvular disease, cardiomyopathy, hypertensive heart disease, and unstable angina were excluded. Two weeks before the test had not used digitalis, propranolol, diuretics and other drugs. Method: The load on the treadmill test starts at 10 watts and increases at 10 watts per minute until the heart rate reaches 85% of the maximum heart rate. Flat test using Bruce grading. Isopropyl adrenaline infusion starts at 1 microgram / minute and increases 1 microgram / minute every three minutes until the heart rate reaches 130 beats / min. Dopamine instillation from 200 micrograms / minute
