Acute Right Ventricular Infarction Mimicking Extensive Anterolateral Wall Injury

A patient presented with an acute right ventricular infarction characterized by an electrocardiographic current of injury in both the inferior (2,3,aVF) and anterior precordial leads (V 1 -V 6 ). Cardiac catheterization demonstrated normal left ventricular wall motion, a codominant circulation, and severe disease of the right coronary artery. We propose that this coronary anatomy explains the injury currents on the electrocardiogram. This case illustrates a rare presentation of right ventricular myocardial infarction mimicking an extensive anterolateral wall injury.
