Abstract

Abstract: The application of echocardiography (UCG) combined with electrocardiogram (ECG) in the differential diagnosis of dilated cardiomyopathy (DCM) and ischemic cardiomyopathy (ICM) was analyzed. 80 cases of DCM (group DCM) and ICM (group ICM) in our hospital were selected as the subjects of study from December 2015 to December 2018. The two groups were examined by UCG and ECG and analyzed and compared. The results showed that the incidence of ventricular wall segmental dyskinesia, left ventricular apical round and thin, left ventricular circular arch, and ventricular wall motion of DCM group was significantly lower than ICM group, the incidence of diffuse ventricular wall movement disorder and left ventricle sphericity of group DCM was significantly higher than that ICM group, the difference was statistically significant (P<0.05). The left atrial diameter, left ventricular diastolic diameter, left ventricular systolic diameter, right ventricular diameter, mitral valve E point to interventricular septum spacing, E/A, RV6 and RV6/RMAX of DCM group were significantly higher than those in ICM group, the aorta, left ventricular ejection fraction and stroke volume of DCM group were significantly lower than that in group ICM, the difference was statistically significant (P<0.05). The degree of reflux of aortic valve, mitral valve and three tips of DCM group was significantly higher than that ICM group, the difference was statistically significant (P<0.05). Table four showed that the sensitivity, specificity and accuracy of UCG combined with ECG to identify DCM and ICM were 97.50%, 96.25% and 96.88%, respectively. The results were basically the same as the actual results, the difference was not statistically significant (P>0.05). This study confirms that UCG combined with ECG monitoring can provide important reference for the identification of DCM and ICM, and can be used as an important means to identify DCM and ICM, which is worth for further clinical promotion.
