A study of the clinical application value of ultrasound and electrocardiogram in the differential diagnosis of cardiomyopathy

Objective: To investigate the clinical application values of electrocardiogram (ECG) combined with ultrasound cardiogram (UCG) in the differential diagnosis of cardiomyopathy. Methods: A total of 120 patients with cardiomyopathy who were admitted to our hospital were randomly divided into the dilated cardiomyopathy (DCM) group (60 cases) and the ischemic cardiomyopathy (ICM) group (60 cases). Both groups were examined using ECG combined with UCG. The ultrasonic values (aorta, LADI, LVDd, LVESD, RVID, SV, LVEF, LVET, EPSS, E/A, RV6, RV6/RMAX), morphological changes (thin and round left ventricular apex, spherical left ventricle, arch-shaped left ventricle, segmental wall-motion abnormalities (SWMAs), diffuse wall motion abnormalities (DWMAs), paradoxical ventricular wall motion) and heart valve regurgitation (aortic valve, mitral valve, tricuspid valve, pulmonary valve) were compared and analyzed. Results: The degree of chamber enlargement in the DCM group was remarkably higher than that in the ICM group, but the degree of LVEF and aortic enlargement were significantly lower than those in the ICM group (P
