Original abstract
A previously healthy and normally developing 12-day-old female suddenly became restless and developed cold sweats, tachypnoea and tachycardia (300 beats/min). Neither electrocardiogram nor echocardiogram showed evidence of any cardiac defect. Carotid sinus massage and other vagus-stimulating manoeuvres, undertaken because paroxysmal supraventricular tachycardia (PSVT) was suspected, were unsuccessful. Before rapid digitalization, adenosine triphosphate was administered (0.1 mg/kg intravenously). Sinus rhythm was restored within about 60 s. Despite further treatment with digoxin and verapamil (4 mg/kg.d), further episodes of PSVT occurred, each again responding to ATP (0.1 to 0.3 mg/kg). There were no side effects. After 24-hour Holter ECG monitoring had revealed Wolff-Parkinson-White syndrome as cause of the PSVT, propafenone was administered (15 mg/kg daily) and has prevented further recurrence of the tachycardia.
