ST段偏移在冠心病诊断中的临床意义研究

Clinical significance of ST segment shift in diagnosis of coronary heart disease

为探讨动态心电图ST段偏移对诊断冠心病的临床价值,观察经冠状动脉造影主要分支狭窄≥50％的62例冠心病组与101例正常健康老人组的最大ST段上抬、最大ST段下移、ST段偏移总和、ST段偏移总差等参数。结果两组间除ST段偏移总和外,其余参数均有显著性差异(P<0.001)。初步提示这些参数可作为诊断冠心病的鉴别诊断依据,但对上述参数的正常值范围尚需作进一步的研究。

In order to investigate clinical significance of ambulatory ECG ST segment shift in diagnosis of coronary heart disease (CHD), we were observed parameters of maximum elevation of ST segment, maximum depression of ST segment, total sum of ST segment shift and deviation of shift of ST segment, among 62 cases of CHD with main fascicular narrowness≥50% by coronary angiography and 101 cases healthy elderly subjects. Results showed except total sum of ST segment shift, all parameters, had significant difference between two groups ( P <0. 001), preliminary indicating these parameters might be helpful in differential diagnosis. But further research is needed for establishment of normal ranges of above parameters.
