General practitioners in one health district were surveyed by postal questionnaire (including 15 sample electrocardiogram tracings) to assess their usage and competence in interpretation of the electrocardiogram. A response rate of 60% was achieved, of whom 40% said they used the electrocardiogram at least monthly and 43% used it 'always' or 'usually' in patients with suspected myocardial infarction at home. Overall competence in recognizing a variety of abnormalities was felt to be good. Recent qualification, the possession of a higher qualification (MRCP/MRCGP) and frequency of usage were associated with better performance. Even so, unequivocal acute myocardial infarction was misdiagnosed by 20% of respondents. These findings have implications for the provision of electrocardiographic services in primary care and the management of patients in the home with suspected myocardial infarction, particularly with the advent of thrombolytic therapy.
通过邮寄问卷（包括15份心电图样本）对一个健康区的全科医生进行了调查，以评估他们对心电图的使用情况和解读能力。问卷回复率为60%，其中40%的人表示他们至少每月使用一次心电图，43%的人在怀疑家中患者发生心肌梗死时“总是”或“通常”使用心电图。总体而言，识别各种异常的能力被认为良好。近期获得资格、拥有更高资格（MRCP/MRCGP）以及使用频率与更好的表现相关。即便如此，20%的受访者仍误诊了明确的急性心肌梗死。这些发现对初级保健中提供心电图服务以及在家中对疑似心肌梗死患者的管理具有启示意义，尤其是在溶栓治疗出现之后。
