Title: Electrocardiographic Changes in Right Ventricular Infarction
Abstract: ABSTRACT. ST segment elevations in leads CR 4 R or V 4 R indicating right ventricular (RV) involvement are sometimes seen in patients with acute inferior transmural infarction. Whether the RV lesion per se or the concomitant infarction of the posterior septum causes this ECG pattern is unknown. We describe a patient with anteroseptal transmural infarction who developed unusually marked ST segment elevations in lead V 4 R. At autopsy, extensive old fibrotic infarction was found, involving the anterior and lateral RV walls, as well 89 recent necrosis of the interventricular septum. These findings suggest that the ST segment elevation in V 4 R in patients with RV infarction may not be caused by the RV necrosis per se but rather by visualization of the posterior septum through the necrotic RV myocardium.
