经临床诊断为冠心病的住院患者106例,男88例,女18例,年龄27～68(平均50±8.5)。根据冠状动脉造影结果.将106例分为冠状动脉造影正常、单支病变、双支病变及三支病变(冠状动脉病变指狭窄程度在50％以上者)四组。分别为26、30、20、30例。其中出现Tv_1>Tv_6及/或T_M>T_1者分别为8、9、10、18例,仅三支病变组与正常组比较有显著性差异(P<0.05)。Tv_1>Tv_6及T_M>T_1对冠心病的诊断效率为51.4％。 T波在对应导联发生改变,出现T_M>T_1、Tv_1>
The clinical diagnosis of coronary heart disease inpatients 106 cases, 88 males and 18 females, aged 27 to 68 (mean 50 ± 8.5). According to the result of coronary angiography, 106 cases were divided into four groups: normal coronary angiography, single vessel lesion, double vessel lesion and three vessel lesion (coronary lesion refers to more than 50%). Respectively, 26,30,20,30 cases. Tv_1> Tv_6 and / or T_M> T_1 were 8, 9, 10 and 18 cases, respectively. There were significant differences between the three lesion groups and the normal group (P <0.05). The diagnostic efficiency of Tv_1> Tv_6 and T_M> T_1 for coronary heart disease was 51.4%. T wave in the corresponding lead changes, appear T_M> T_1, Tv_1>
