本文心得安试验显示综合征阳性率(67％)不如心脏神经宫能症(82％),两者差异达显著意义(U=14.09(>2.58),P<0.01);而心电图运动试验则前者阳性率(100％)高于后者(30％),且达到差异显著(U=16.73(>2.58),P<0.01)。并结合其它临床资料可初步区别两者的不同存在形式;但对综合征与冠心病心绞痛的判别尚需选择性冠状动脉造影。
The trial of propranolol showed that the positive rate of syndrome (67%) was not as good as that of cardiac neuroma (82%), the difference was significant (U = 14.09 (> 2.58), P <0.01) The positive rate (100%) was higher than the latter (30%), and the difference was significant (U = 16.73 (> 2.58), P <0.01). Combined with other clinical data can be the initial difference between the two forms of existence; but the syndrome and coronary heart disease angiography still need selective coronary angiography.
