本文对３１例正常人、３４例心肌缺血及１７例心肌梗塞进行靶心图定量分析，并与断层显像及靶心图定性分析进行了比较。结果表明：三种方法诊断心肌缺血的灵敏度与特异性依次为８８．２％、９１．２％和９４．１％（Ｐ＞０．０５）；９３．５％、８３．９％和８３．９％（Ｐ＜０．０５）。定量分析对心梗周围缺血心肌壁段的检出率明显高于后两种方法（Ｐ＜０．０１）。因此，靶心图定量分析为诊断冠心病提供了一种客观、定量、特异和灵敏的方法。
In this paper, 31 cases of normal subjects, 34 cases of myocardial ischemia and 17 cases of myocardial infarction targeted bullogastric quantitative analysis, and qualitative imaging and the bull’s eye were compared. The results showed that the sensitivity and specificity of the three methods were 88.2%, 91.2% and 94.1% (P> 0.05), 93.5%, 83.9% and 83% respectively .9% (P <0.05). Quantitative analysis of ischemic myocardial infarction around myocardial wall detection was significantly higher than the latter two methods (P <0.01). Therefore, quantitative target bull’s eye diagram provides an objective, quantitative, specific and sensitive method for the diagnosis of coronary heart disease.
