Abstract

This study determined quantitative ST segment changes on the 18-lead electrocardiogram (ECG) during occlusions in each of the coronary arteries. Methods: Continuous 18-lead ECGs, including standard 12 leads, posterior (V_7-9), and right ventricular (RV) leads (V_3-5R) were recorded for 155 subjects undergoing percutaneous coronary occlusions, the maximum intervention. Results: During 58 left anterior descending (LAD) coronary occlusions, the maximum ST elevation and depression were in V₃ (4.2mm) and III (-0.9mm), respectively. During 44 right coronary artery (RCA) occlusions, the maximum ST elevation and depression were in III (2.2mm) and aVL (-1.4mm), respectively. During 53 left circumflex (LCX) occlusions, the maximum ST elevation and depression were in V₇ (0.8mm) and V₂ (-1.6mm), respectively. Conclusions: ST elevation often occurred in the anteroapical (V₁-V₆), lateral (I, aVL), and RV lead V_3R during LAD occlusions; in the inferior, RV, and posterior leads during RCA occlusions; and in the posterior, inferior, and apical leads (V₅-V₆) during LCX occlusions.
