Sirs: A 13-year-old girl was referred to our hospital because of recurrent dizziness and palpitations. On admission, several twelve-lead ECG recordings showed an incessant ventricular tachycardia (VT) with an inferior axis and a left bundle branch block pattern (approximately 130 beats/min; Fig. 1a). There was a history of palpitations (for 1 month), but no structural heart disease. The tachycardia was poorly tolerated by the patient. She suffered from severe dizziness during VT episodes and was transferred to the intensive care unit. Laboratory tests did not reveal any abnormalities and there was no evidence for myocardial ischemia or an acute inflammatory process.
