Abstract

OBJECTIVE: There are controversies about the relation between infarction localization and late potentials (LP) following acute myocardial infarction (AMI). To evaluate this issue 124 consecutive patients with first Q-wave AMI fulfilling the inclusion criteria were enrolled in this signal--averaged ECG (SAECG) study. METHODS: The patients were divided into three groups according to infarction localization: anterior (Group I n = 62; 50%), inferior (Group II: n = 42; 34%) and both inferior and right ventricular (RV) involvement (Group III n = 20; 16%). SAECG records were performed during the second week. LP results were evaluated as positive when at least two of the major criteria (QRS > 114 ms, LAS 40 > 38 ms, RMS < 20 µV) were obtained. Tukey--Cramer multivariate analysis was performed. RESULTS: Positive LP results were obtained in 29% of group I, 35.7% of group II and 55% of group III patients. Patients with both inferior and RV involvement had a significantly higher positive LP results independent from left ventricular ejection fraction. CONCLUSION: Therefore, increased risk of arrhythmia in those patients with both inferior MI localization and RV involvement should be taken into consideration.

Özet

Amaç: Miyokard infarktüsü lokalizasyonu ile geç potansiyeller (GP) arasındaki ilişki tartışmalıdır. Bu konuyu değerlendirmek amacıyla planlanan sinyal ortalamalı EKG (SOEKG) çalışmasına daha önce miyokard infarktüsü anamnezi olmayan 124 ardışık Q dalgalı akut miyokard infarktüsü (AMİ) hastası (104 erkek, 20 kadın; ortalama yaş 56 ± 10) katıldı. Yöntem: Hastalar infarktüs lokalizasyonuna göre üçe ayrıldı: anteriyor (Grup I, n = 62 ; % 50 ), inferiyor (Grup II, n = 42; %34) ve inferiyor +sağ (Grup III, n = 20 ; % 16 ). SOEKG ikinci hafta içinde yapıldı. GP pozitifliği üç major kriterden (QRS > 114 ms, LAS 40 >38 ms , RMS< 20 mV) en az ikisinin sağlanması olarak kabul edildi. Tukey - Cramer multivaryans analizi yapıldı. Bulgular: İnferiyor + sağ AMİ olan vakalarda GP pozitifliği, diğer gruplara göre anlamlı olarak daha yüksek bulundu (Grup I de %29 , II de %35.7 ve III de %55, p < 0.05). Bu fark sol ventrikül ejeksiyon fraksiyonundan bağımsız idi. Sonuç: Bu bulgulardan hareketle inferiyor ve sağ ventrikül infarktüsünün birlikte olduğu hastalarda aritmi riskinin artmasının söz konusu olabileceği düşünülebilir.
