Electrocardiogram (ECG) is a simple, readily affordable, and noninvasive tool for the evaluation of cardiac disorders. There is a dearth of information on the utility of ECG in general practice in Nigeria. We assessed the knowledge and utilization of ECG among family medicine residents in Nigeria.
A cross-sectional evaluation was conducted between November 2011 and May 2012 in four family medicine training centers in Nigeria. A self-administered questionnaire was used to obtain information from the resident doctors regarding their ECG requests, preferred source of interpretation, most common ECG diagnosis, and update of ECG knowledge.
Only 61 out of 120 questionnaires (50.8%) were returned. The respondents were mostly between 31 and 40 years (54.7%) and were predominantly males (73.8%) and senior residents (65.6%). Fifty-four (88.3%) respondents made <5 ECG requests/week, and the most common indication was hypertension (50%). ECG interpretation was either self-reported (41%), by a cardiologist (26.5%), or automated reports (21.3%). Self-reporting of ECG was more common among senior residents (P < 0.01). Left ventricular hypertrophy was the most common ECG diagnosis (55.8%). About 69% of respondents did not update their knowledge of ECG. Most respondents (50%) reported basic interpretation as the aspect of ECG for which further learning was desired. Teaching ECG to resident doctors in the update courses of the postgraduate medical colleges and continuing medical education (CME) activities was adjudged the best way to improve knowledge/utility (61.1%).
The attitude to and utility of ECG among family medicine residents in Nigeria is poor. Improved knowledge, attitude, and utilization of ECG through curriculum revision, hands-on tutorials, and CMEs are highly recommended.
心电图（ECG）是一种用于评估心脏疾病的简单、价格低廉且无创的工具。在尼日利亚的普通医疗实践中，关于心电图效用的信息匮乏。我们评估了尼日利亚家庭医学住院医师对心电图的了解和使用情况。
2011年11月至2012年5月期间，在尼日利亚的四个家庭医学培训中心进行了一项横断面评估。使用一份自填式问卷从住院医生那里获取有关他们的心电图申请、首选解读来源、最常见的心电图诊断以及心电图知识更新情况的信息。
120份问卷中仅61份（50.8%）被收回。受访者大多年龄在31至40岁之间（54.7%），主要为男性（73.8%）和高级住院医师（65.6%）。54名（88.3%）受访者每周进行的心电图申请少于5次，最常见的指征是高血压（50%）。心电图解读要么是自我报告（41%），由心脏病专家解读（26.5%），要么是自动报告（21.3%）。高级住院医师中自我报告心电图解读的情况更为常见（P < 0.01）。左心室肥大是最常见的心电图诊断（55.8%）。约69%的受访者未更新他们的心电图知识。大多数受访者（50%）表示基础解读是他们希望进一步学习的心电图方面。在研究生医学院的更新课程和继续医学教育（CME）活动中向住院医生教授心电图被认为是提高知识/效用的最佳方式（61.1%）。
尼日利亚家庭医学住院医师对心电图的态度和使用情况较差。强烈建议通过课程修订、实践教程和继续医学教育来提高对心电图的知识、态度和使用。
