Infantile hypertrophic cardiomyopathy with QT prolongation.
A neonate presented with neonatal myocardial dysfunction and long QT interval with subsequent appearance of hypertrophic cardiomyopathy at one week of age. Maternal glucose metabolism was normal. By 15 months of age the hypertrophy had largely resolved but the long QT persisted. The possible relationship between these conditions is discussed.
