摘要
对67例冠心病患者及45例正常人进行经食管心房调搏分级心向量图负荷试验。结果发现,负荷后T向量、T长/宽、R向量/T向量的阳性改变对诊断冠心病有重要的临床价值,而ST向量、T环转向异常及T环等速运动等,虽特异性很高,但敏感性较低;并据此提出试验的诊断标准。
Sixty-seven patients with coronary heart disease and forty-five normal subjects were studied by vectorcardiographic load test via transesophageal atrial pacing. The results showed that sensitivity of the test was significantly higher than that of bicycle ergometer test. The changes of T vector,reduction of the ratio between length and width of T vector and increase of the ratio between R vector and T vector had important value in diagnosis of coronary heart disease, and the specificity of ST vector, abnormal turning of T loop and equal speed circulation of T loop was high but the sensitivity was low in diagnosis. The diagnostic criteria of the test were suggested.
