Brugada ECG Pattern Unmasked by IV Flecainide in an Individual with Idiopathic Fascicular Ventricular Tachycardia
نویسندگان
چکیده
A 45-year old man presents with stable monomorphic ventricular tachycardia. He had previously been diagnosed with idiopathic fascicular ventricular tachycardia. Intravenous flecainide results in termination of his tachycardia but unmasks a latent type 1 Brugada ECG pattern not seen on his resting ECG. We discuss his subsequent management and the need to consider an alternative diagnosis in individuals with a Brugada type ECG pattern who present with stable monomorphic ventricular tachycardia.

BACKGROUND Many subjects in community have non-type 1 Brugada pattern ECG with atypical symptoms, relevance of which is not clear. Provocative tests to unmask type 1 Brugada pattern in these patients would help in diagnosing Brugada Syndrome. However sensitivity and specificity of provocating drugs are variable. METHODS We studied 29 patients referred to our institute with clinical presentati...

BACKGROUND Whether Brugada syndrome (BrS) depends on functional epicardial substrates, which may be definitively eliminated by radiofrequency ablation, remains unknown. METHODS AND RESULTS Patients with BrS underwent epicardial mapping to identify areas of abnormal electrograms as target for radiofrequency ablation. Substrate identification consisted in mapping right ventricle epicardial surf...

Introduction Verapamil-sensitive fascicular ventricular tachycardia (VT) is the commonest form of idiopathic left ventricular tachycardia (ILVT). The characteristic diagnostic features of fascicular ILVT include: (i) induction with atrial pacing, (ii) right bundle branch block (RBBB) with left-axis deviation morphology during VT, (iii) absence of structural heart disease, and (iv) verapamil sen...
