目前国内外关于心得安试验对冠心病心电图运动试验的诊断价值,尚无一致的意见。多数报道认为可以用心得安试验鉴别女性心电图运动试验的假阳性,从而以此排除冠心病。鉴于上述情况,为了弄清心得安试验的价值,我们对33例临床确诊为冠心病的病人进行了试验,结果表明心得安试验没有鉴别诊断价值。现将试验的结果报告如下。试验方法与结果我们采用口服心得安20mg,分别在服药后1小时和2小时描记休息时心电图,与服药前休息时心电图比较。若属运动试验阳性者,于当日服20mg心得安,分别在服药后1小时和2小
At present, there is no consistent opinion on the diagnostic value of propranolol on ECG test of coronary heart disease. Most reports suggest that a trial of authenticity can be used to identify the false positives of a female ECG exercise to exclude coronary heart disease. In view of the above, in order to clarify the value of propranolol, we conducted a trial of 33 patients with clinically diagnosed coronary heart disease. The results showed that propranolol did not have a differential diagnostic value. The test results are reported below. Test Methods and Results We used oral propranolol 20mg, respectively, at 1 hour and 2 hours after taking the resting electrocardiogram, compared with resting before taking the ECG. If the motor test positive, on the day of service 20mg propofol, respectively, after taking 1 hour and 2 hours
