A correlation study for detection of Left Atrial Enlargement of patients with cardiac and non cardiac disease: A hospital based study

Objective: Our study was to detect the prevalence and correlation of echocardiography and ECG finding of left atrial enlargement of patients with cardiac and non cardiac disease. Methodology: A total of 75 patients were included on the basis of inclusion criteria. A detail assessment was taken to all patients. A standard 12 lead ECG was recorded and Echocardiography was performed in all the cases. Left atrial size was measured by 2D echo guided M-mode echocardiography. Results: Data was analyzed by using MS-Office software. Conclusions: Patients with RHD with mitral and aortic valve disease, hypertension, atrial fibrillation and IHD were more associated to left atrial enlargement (LAE). 2 D echocardiography was able to categorize LAE into mild, moderate and severe. ECG was only able to predict LAE. Hence echocardiography is superior than electrocardiography for detection of LAE.
