title: [Ortodromic atrio-ventricular reentrant tachycardia with functional left bundle branch block morphology - differential diagnosis of wide complex tachycardia based on case report].
abstract: We present a case of 18 year-old man, without structural heart disease, who suffered from regular and irregular palpitations. ECG was normal during sinus rhythm, and showed LBBB morphology during tachycardia (220/min). Programmable pacing from CS induced sustained atrial fibrillation with normal and wide QRS (LBBB-like, RBBB-like) and minimal RR interval 270 ms. We found and ablate concealed left free wall accessory pathway. During 1-year observation patient stayed asymptomatic.
