[Acute isolated ischemia of the right ventricle with ST elevation in V1 to V4].

An acute anteroseptal infarction was diagnosed in a 51-year-old man whose ECG showed ST elevations in leads V1-V4 after acute retrosternal pain for about 20 min. Angiography revealed proximal occlusion of the right coronary artery, while the dominant left coronary artery was fully patent. After successful recanalization of the right coronary artery with intracoronary infusion of urokinase, the ST elevations quickly disappeared and impending right-heart infarction was avoided. Isolated right-heart infarction can imitate the ECG pattern of anteroseptal infarct and should be considered if the height of ST elevations diminishes from V1 to V4.
