Atrial Fibrillation is the most commonly encountered irregular heart beat (arrhythmia) in our population. Its prevalence though less than 1 % in general population below 65 years old, its incidence and prevalence is in increasing trend. Initially asymptomatic in due course they will land up with lot of complications. Echocardiography is useful to find out the causes for development of atrial fibrillation and various echocardigraphic parameters predicts risk for future development of atrial fibrillation and complications associated with atrial fibrillatio.
Methodology: 100 patients with atrial fibrillation were analysed. Evaluation regarding etiology of AF is done by using ECG and Transthoracic echocardiogram, Chest radiograph were done in all patients. Thyroid Function tests were done only for ‘at risk’ cases and those who are presenting with signs and symptoms of hyperthyroidism.
Results: Out of 100 total patients 68 were females, 32 were males. The number of patients with RHD were 77, and the remaining 23 cases had Non RHD etiological factors.
Conclusion: Most common symptom in our study was palpitation. Most common etiology was Rheumatic heart disease with Mitral stenosis. Few Patients with severe MS presented with LA clot.
