Abstract

Objectives: We aimed to investigate the predictive value of lead aVR in the evaluation of electrocardiograms (ECG) for lesions in the proximal portion of the left anterior descending (LAD) coronary artery.Study design: The study consisted of 361 patients (293 males, 68 females; mean age 58±10 years; range 24 to 84 years) with acute myocardial infarction (AMI), who presented with typical chest pain and ST elevation on ECG. All of the patients underwent coronary angiography (CAG) in order to identify the infarct-related artery (IRA) and its segments. Changes in the ST segment (i.e. elevation or depression) were evaluated in all leads including aVR. The patients were divided into two groups according to the ST elevation recorded in lead aVR, namely as positive (≥0.5 mm) or negative (

Özet

Amaç: Bu çalışmada son zamanlarda elektrokardiyografinin (EKG) değerlendirilmesinde kullanımı gündeme gelen aVR derivasyonun, sol ön inen arter (SİA) proksimal lezyonlarını belirlemedeki değeri araştırıldı.Çalışma planı: Çalışmaya, tipik göğüs ağrısı nedeniyle hastaneye başvuran ve EKG’de tipik ST yükselmesi görülen akut miyokard infarktüslü (AMİ) 361 hasta (293 erkek, 68 kadın; ort. yaş 58±10; dağılım 24-84) alındı. Hastaların hepsine koroner anjiyografi (KAG) yapılarak infarktüsten sorumlu arter (İSA) ve segmenti saptandı. Elektrokardiyografi değerlendirmesinde her bir derivasyonda ve aVR’de meydana gelen ST yükseklikleri ve çökmeleri kaydedildi. Hastalar aVR’de ≥0.5 mm ST yüksekliği varlığına göre aVR pozitif (+) ve negatif (-) olmak üzere iki gruba ayrıldı.Bulgular: Elektrokardiyografi değerlendirmesinde, aVR (+) grupta hastaların %54’ünde infarktüsten sorumlu arter SİA proksimali iken, aVR (-) grupta bu oran %9 idi (p
