[ST-segment shift in V1-V3 in patients with inferior wall infarction depend on angiographic localization of right artery occlusion]

Two electrocardiographic types of inferior wall infarct were isolated based on angiographic localization of right coronary artery occlusion. In proximal occlusion of RCA before right ventricular branch there is no depression or more rarely elevation of ST segment in V1-V3 especially in V1 (the first morphological type). ST segment depression in V1-V3 (second morphological type) is characteristic for distal segment of RCA occlusion.
