N2 - Five children are described who had persistent, chronic tachycardia and left ventricular dysfunction manifested by decreased left ventricular percent fractional shortening on echocardiogram (five patients) cardiomegaly on chest roentgenogram (three), ventricular or atrial hypertrophy on ECG (three), and symptoms of congestive heart failure (three). After antidysrhythmia therapy and control of the tachycardia, signs and symptoms of congestive heart failure resolved in two infants. Moreover, in each patient signs of cardiomegaly resolved on chest roentgenogram, hypertrophy resolved on ECG, and the fractional shortening improved to normal (mean 20.2%±2.4% SEM before vs 36.2%±2.4%, P=0.02, after treatment). Evaluation in the child who has dilated cardiomyopathy should include assessment of heart rate and rhythm. Moreover, when persistent tachycardia is found in an asymptomatic child, evaluation of left ventricular function is indicated.
