In this study the majority of the patients (78), i.e., 22.03% were in the age group of 61–70 years. Majority of the patients were female (58.19%). Males comprised of 41.81%. The common symptoms of atrial fibrillation in the patients were palpitation 85.31% and breathlessness 82.77%. Next common symptoms were fatigue 73.16%, PND 70.06% and swelling of dependant parts 68.93% respectively. Giddiness 57.91% and orthopnea 53.67% were the next common presenting symptoms. Chest pain was the presenting complaint in 22.32% cases and limb weakness or stroke in 7.34% cases. Involuntary movements 3.95% and sleep apnea 1.97% were among the least common symptoms observed, while 2.82% cases were asymptomatic. Among the clinical signs of atrial fibrillation, the most common signs were pulse deficit 77%, raised JVP 74%, pedal edema 68.9%, CCF 68.6%, (LV or RV) S3 52% respectively. Icterus 9.32%, cyanosis 8.47% and clubbing 4.24% were found as minor signs. Maximum 50.56% AF cases were found in the systolic BP ranging from 121 to 160, followed by 33.05% in 80–120 range. Least 16.38% patients were encountered in the systolic BP ranging from 161 to 200. Maximum 74.01% cases were found in the diastolic BP ranging from 71 to 100, followed by 50–70 range in 25.71% cases. As regard to pulse pressure maximum cases were found in the >40 group amounting to 72.88% cases. In the ≤40 group only 27.12% cases were there.
