ABSTRACT… Objectives: To determine the frequency and contributing factors of atrial fibrillation in patients with first ischemic stroke. Methodology: This study included 150 patients with first acute ischemic stroke. All the patients had electrocardiography to detect the presence of atrial fibrillation. The patients were also labeled for risk factors like hypertension, congestive heart failure, smoking, and hyperthyroidism, etc. Setting: Mayo Hospital Lahore. Duration of Study: 1 st January 2013 to 30 th June 2013. Type: Descriptive Cross Sectional. Results: Atrial fibrillation was present among 22 (14.6%) patients. Among patients with atrial fibrillation, smoking, congestive heart failure and hypertension were the most frequent risk factors which were present in 11 (50%), 6 (27%), and 5 (22.7%) patients, respectively. Conclusion: Frequency of atrial fibrillation among patients with first ischemic stroke was high. Smoking, congestive heart failure and history of coronary artery bypass grafting are frequent risk factors.
