【摘要】 目的探讨超声心动图在慢性肺源性心脏病中的诊断价值,并与心电图进行比较。方法选取医院确诊的慢性肺源性心脏病患者128例为观察组,健康体检者120例为对照组,所有入组者均进行超声心动图、心电图检查,比较2种检查方法的诊断价值。结果观察组患者收缩期右房横径(RA)、舒张末期右室横径(RV)、右心室前壁厚度(RVAWT)、肺动脉主干内径(MPA)及肺动脉收缩压(PASP)数值均高于对照组(P<0.05);超声心动图检查诊断阳性率为82.03%,高于心电图的68.75%(P<0.05);2种检查方法对右心扩大伴右心衰竭患者的诊断阳性率均高于单纯右心扩大(P<0.01)。结论在慢性肺源性心脏病的诊断中,超声心动图可有效提高准确率,为临床诊断提供依据。更多还原

【Abstract】 Objective To investigate the diagnostic value of echocardiography in chronic cor pulmonale and compare with electrocardiogram. Methods 128 patients with chronic cor pulmonale were selected as the observation group and 120 healthy subjects as the control group. All patients were evaluated by echocardiography and electrocardiogram. The diagnostic value of the two methods was compared. Results The right atriumdimension diameter( RA),right ventricular diameter( RV),right ventricular anterior wall thickness( RVAWT),the main pulmonary artery diameter( MPA) and pulmonary artery systolic pressure( PASP) of patients with chronic cor pulmonale were significantly higher than medical health population( P <0. 05). The positive rate of echocardiography was 82. 03%,significantly higher than that of 68. 75% of using electrocardiogram( ECG)( P < 0. 05). Statistical analysis suggested that both echocardiography and electrocardiogram. The diagnostic accuracy of the two methods in patients with right heart enlargement and right heart failure was higher than that of simple right heart enlargement( P < 0. 01). Conclusion Echocardiography was found to be a reliable method of assessing right ventricular function in patients with chronic cor pulmonale,which provided the basis for clinical diagnosis.更多还原
