Abnormalities in the aVR lead would provide useful information on the risk of coronary heart disease. This clinical case is an illustration. Indeed, this is a 60-year-old patient, an active smoker and a former type 2 diabetic who presented with angina-like chest pain with a positive stress test. The initial electrocardiogram showed a discreet elevation of the ST segment and an aVR necrosis Q wave with mirror signs in the inferior territory. An ischemic heart disease with altered ventricular ejection fraction was objectified. The diagnostic coronary angiography objectified a multi-vessel coronary lesion. Ultimately, the aVR lead provides valuable clinical information and argues for special attention to this often forgotten lead.
aVR导联的异常可为冠心病风险提供有用信息。本临床病例就是一个例证。的确，这是一名60岁患者，长期吸烟，曾患2型糖尿病，出现类似心绞痛的胸痛，运动试验呈阳性。最初的心电图显示ST段轻度抬高，aVR导联有坏死Q波，下壁导联有镜像改变。确诊为缺血性心脏病伴心室射血分数改变。诊断性冠状动脉造影显示多支冠状动脉病变。最终，aVR导联提供了有价值的临床信息，提示应特别关注这一常被忽视的导联。
