Idiopathic ventricular tachycardia (VT) represents a common form of ventricular arrhythmias in patients with structurally normal hearts. Due to lack of clinical studies the long-term outcome in this group remains uncertain. A 21-year-old male admitted to ED with recurrent palpitations, dyspnea and lightheadedness. He experienced rare episodes of palpitation during last 6 months without syncope. Family history was unremarkable while his grandmother had dead born child. On admission ECG showed sinus rhythm with signs of early repolarization syndrome and short corrected QT interval of 28 ms. During his evaluation in the ED palpitations recurred and ECG showed frequent ventricular premature complexes transforming into non-sustained VT with QRS duration of 0.16 ms that was spontaneously converted to sinus rhythm. The patient was started metoprolol 50 mg a day. Holter monitoring revealed four episodes of asymptomatic non-sustained monomorphic VT and demonstrated short corrected QT interval under 32 ms. MRI scan showed structurally normal heart while genetic tests didn’t reveal arrhythmogenic right ventricular dysplasia mutation and patient was diagnosed idiopathic VT. He continued b-blockers and remained asymptomatic during 10 months follow-up.
