The literature on isolated right ventricular infarction is reviewed and local experience is reported. Chronic lung disease is an important risk factor. Chest pain and breathlessness are common. Syncope and sudden collapse can also occur. Rhythm disorders include sinus bradycardia, atrial fibrillation and ventricular tachycardia or fibrillation. Atrioventricular block is rare. Hypotension and a right-sided fourth heart sound are common. Cautious use of slow-release nitroglycerin is not hazardous in the absence of hypotension. High doses of steroids and anticoagulants can be helpful. The prognosis is usually good, although sudden collapse can occur due to ventricular fibrillation, rupture of the right ventricular free wall or massive pulmonary embolism.
