The ECG is abnormal, and the CXR shows a normal cardiac silhouette.For the above patient with shortness of breath and peripheral edema, select the most likely diagnosis.
RVMI is characterized by high neck veins, ECG abnormalities, and often a right-sided S3. The low cardiac output associated with RVMI can often be treated by volume expansion. Although a third of patients with inferoposterior infarctions have some degree of right ventricular necrosis, extensive RVMI is uncommon.
