The relative incidence may reflect the severity of the heart disease since most of the infants studied were critically ill. Twelve of the 13 patients less than 60 days old in whom ventricular fibrillation developed had coarctation tion of the aorta, aortic stenosis, hypoplasia of the left heart, or mitral atresia. Patients with these diagnoses represented approximately 10% of all patients under the age of 60 days who were studied.
