Özet
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 V) 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.
