A boy with a birth weight of 3.030 g was born by caesarean section at 33 weeks of gestation because of bradycardia and severe foetal hydrops. Physical examination at birth showed a hydropic neonate with a heart rate of 70 beats/min. He had cutaneous syndactyly between the fourth and fifth fingers of the left hand. During the first week of life he suffered from polymorphic ventricular arrhythmias for which β- blocker treatment was started and an epicardial pacemaker (VVI) was implanted. An ECG a few weeks later is shown in the figure.
