[Contribution of the AVR lead in the diagnosis of ischemic heart disease in one case at the Institute of Cardiology of Abidjan (Ivory Coast)].

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.
