ACUTE RIGHT-VENTRICULAR INFARCTION MIMICKING EXTENSIVE ANTEROLATERAL WALL INJURY

A patient presented with an acute right ventricular infarction charact erized by an electrocardiographic current of injury in both the inferi or (2,3,aVF) and anterior precordial leads (V1-V6). Cardiac catheteriz ation demonstrated normal left ventricular wall motion, a codominant c irculation, and severe disease of the right coronary artery. We propos e that this coronary anatomy explains the injury currents on the elect rocardiogram. This case illustrates a rare presentation of right ventr icular myocardial infarction mimicking an extensive anterolateral wall injury.
