| 摘 要： | 目的：研究利用心电图诊断右心室肥大的临床指标，探讨提高其临床诊断率的方法。方法：筛选出右室肥大患者心电图记录75例，正常对照组30例；分别采集传统诊断方法和改进方法所需各项指标，并分别加以判断。结果：传统组合诊断指标的灵敏度为85.3％，特异度为93％；改进的组合诊断指标灵敏度为96％，特异度为100％。结论：由QRS波群面积、倒置T波面积、心电轴右偏度数组成的改进指标是心电图诊断右室肥大最重要的指标。 |

| Abstract: | To study the clinical indexes of the Right Ventricular Hypertrophy （RVH） diag-noses by the ECG, and the more effective techniques of the clinical diagnosis. Method： 75 cases of RVH and 30 cases of normal. Both the traditional method and the new method are adopted to analysize respectively. Result： The check computations show that, the traditional diagnosis has the sensitivity of 85.3% and the specificity of 93%; the new diagnosis has 96% and 100% correspondingly. Conclusion： The areas of the QRS complexes and the inverts T waves, and the deviation degree of the right axis, are the most important indexes in the diagnosis of the RVH by the ECG. |
