Data were analyzedto determine age based relationship with atrial fibrillation.Results:Atrial fibrillation was observed in 190/458 patients (41.48%) above the age of 50 years who reported withischemic stroke Out of which 112 (58.95%) were male and 78 (41.05%) were female. Atrial fibrillation was observed tobe 11.20% in age group 50-59 years which increases to 39.85 % in the age group 60-69 years and 67.92% in the agegroup 70-79 years.
