[Contribution of the AVR lead in the diagnosis of ischemic heart disease in one case at the Institute of Cardiology of Abidjan (Ivory Coast)]. / Contribution de la dérivation AVR dans le diagnostic de la cardiopathie ischémique: à propos d'un cas à l'Institut de Cardiologie d'Abidjan (Côte d'Ivoire).

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.
