Atrial fibrillation is one of the commonest arrhythmias with an overall prevalence estimated to be 0.4-1% in the general population. The objective of this study was to find out the prevalence of atrial fibrillation among patients admitted to the Department of Internal Medicine in a tertiary care centre.
A descriptive cross-sectional study was conducted among patients admitted to the Department of Internal Medicine of a tertiary care centre from 01 March 2021 to 01 March 2022. Ethical approval was obtained from the Institutional Review Committee (Reference number: IRC-478/2021). Convenience sampling method was used. Data were collected from the hospital records using a semi-structured study proforma including demography, clinical presentation, laboratory investigations, electrocardiogram, 2-dimension echocardiography, and CHA2DS2VASc score. Point estimate and 95% Confidence Interval were calculated.
Among 27,980 patients, atrial fibrillation was found in 185 (0.66%) (0.58-0.77, 95% Confidence Interval). Among them 66 (35.67%) were in the age group of 61-70 years and 97 (52.43%) were females. Dyspnea was present in 149 (80.54%), palpitation in 137 (74.05%) and pedal edema in 117 (63.27%). Valvular atrial fibrillation was seen in 101 (54.59%) and non-valvular atrial fibrillation was seen in 84 (45.41%) patients.
The prevalence of atrial fibrillation was found to be similar when compared to other studies conducted in similar settings.
心房颤动是最常见的心律失常之一，一般人群的总体患病率估计为 0.4-1%。本研究的目的是了解三级保健中心内科住院患者中心房颤动的患病率。
在 2021 年 3 月 1 日至 2022 年 3 月 1 日期间，对三级保健中心内科住院患者进行了一项描述性横断面研究。本研究获得了机构审查委员会的伦理批准（参考编号：IRC-478/2021）。使用便利抽样法。从医院记录中收集数据，使用半结构式研究表格，包括人口统计学、临床表现、实验室检查、心电图、二维超声心动图和 CHA2DS2VASc 评分。计算点估计值和 95%置信区间。
在 27980 名患者中，发现心房颤动 185 例（0.66%）（0.58-0.77，95%置信区间）。其中 66 例（35.67%）年龄在 61-70 岁之间，97 例（52.43%）为女性。149 例（80.54%）出现呼吸困难，137 例（74.05%）出现心悸，117 例（63.27%）出现足踝水肿。101 例（54.59%）为瓣膜性心房颤动，84 例（45.41%）为非瓣膜性心房颤动。
与在类似环境中进行的其他研究相比，本研究发现心房颤动的患病率相似。
