ABSTRACT
We report 3 adolescents with structurally normal heart who were referred to hospital due to long-lasting palpitations. Initial 12-lead-ECG showed sustained, monomorphic ventricular tachycardia, right bundle branch block QRS morphology and axis deviation. After failure of different anti-arrhythmic drugs finally the intravenous medication with verapamil led to termination of ventricular tachycardia in all three patients. All clinical findings and the responsiveness to verapamil are consistent with the diagnosis of idiopathic left ventricular tachycardia. In one patient an electrophysiological study was done and increased left ventricular vulnerability was shown. After inducing a tachycardia originating from the left ventricle radiofrequency catheter ablation of the left-posterior fascicle was successfully performed. The tachycardia was not inducible after this ablation. Since that investigation the patient has been asymptomatic without anti-arrhythmic treatment. Two of three patients have been on oral verapamil prophylactically and have been free of symptoms.
