The prevalence of cardiac arrhythmia (CA) in the Ethiopian population is unknown. A community study was conducted to assess the magnitude and predictors of CAs in adults aged≥40 years in Jimma Town.
A community-based cross-sectional study was conducted in Jimma town from May to July 2017. A total of 634 adults aged 40 years or older were selected using a systematic sampling technique from six kebeles of the Town. Study participants were screened for CA using a 12-lead ECG machine. Face-to-face interviews, anthropometric, important clinical measurements were performed. Data analysis was done using SPSS for windows version 21.0.
A total of 634 study participants, significant CA occurred in 217 individuals (34.2%). Conduction abnormalities and sinus bradycardia were the commonest findings (25.4%). Premature beats (ventricular 1.9%, atrial 1.1%) and atrioventricular nodal reentrant tachycardia (2.1%) were the next most frequent arrhythmias. Arrhythmias were independently associated with smoking(AOR=1.9;P=.047), hypertension(AOR=1.5;P=.02), heart failure(AOR=2.06;P=.023), prior stroke(AOR=4.9;P=.001), previous history of MI(AOR=1.78;P=.039), vigorous intensity activities(AOR=0.56;P=.024), solidified vegetable oil consumption(AOR=3.5;P=.004), and occupation(pensioner, none)[AOR=1.7;P=.017].
CA is highly prevalent in Jimma. Hypertension and history of heart diseases are the most potent predictors of cardiac arrhythmia. Large-scale screening for early detection of arrhythmia has important implications for treatment.
在埃塞俄比亚人群中心律失常（CA）的患病率尚不清楚。本社区研究旨在评估 40 岁以上成年人中 CA 的发生率及其预测因素。
2017 年 5 月至 7 月在 Jimma 镇进行了一项基于社区的横断面研究。采用系统抽样技术从该镇的六个 kebeles 中选择了 634 名 40 岁或以上的成年人。使用 12 导联心电图机筛查研究参与者的 CA。进行了面对面访谈和人体测量、重要临床测量。使用 SPSS for windows 版本 21.0 进行数据分析。
共纳入 634 名研究参与者，有 217 人（34.2%）出现明显的 CA。传导异常和窦性心动过缓是最常见的发现（25.4%）。频发早搏（室性 1.9%，房性 1.1%）和房室结折返性心动过速（2.1%）是下一个最常见的心律失常。心律失常与吸烟（AOR=1.9；P=.047）、高血压（AOR=1.5；P=.02）、心力衰竭（AOR=2.06；P=.023）、既往中风（AOR=4.9；P=.001）、既往心肌梗死史（AOR=1.78；P=.039）、剧烈强度活动（AOR=0.56；P=.024）、食用凝固植物油（AOR=3.5；P=.004）和职业（退休人员，无）[AOR=1.7；P=.017]有关。
CA 在 Jimma 镇的患病率很高。高血压和心脏病史是心律失常的最强预测因素。对心律失常进行大规模筛查对治疗具有重要意义。
