Supraventricular tachycardia may be caused by abnormal conduction pathways such as the Wolf-Parkinson-White syndrome, characterised on the ECG by a short P- R interval and an abnormal delta wave on the upstroke of the QRS complex. The child may develop sudden episodes of tachycardia associated with heart rates of 240beats/min, up to 300beats/min. These appear on ECG as narrow complex rhythms. The child may feel faint and uncomfortable during an arrhythmia.
