Advanced electrophysiological studies and genetic evaluation in a 13-year-old male with tachycardia attacks revealed left posterior fascicular ventricular tachycardia and Brugada type 2 syndrome.
Case Report (n=1)
This case highlights the importance of evaluating underlying genetic causes, such as Brugada syndrome, in patients presenting with seemingly idiopathic left posterior fascicular ventricular tachycardia.

Hypothesis-generating for genetic overlap in fascicular VT and Brugada syndrome; larger studies needed before changing evaluation practices.
A 13-year male patient with a history of tachycardia attacks was diagnosed to have left posterior fascicular ventricular tachycardia (VT) according to the electrocardiogram (ECG) obtained at the emergency service. This diagnosis was confirmed with advanced electrophysiological studies and the case was diagnosed by genetic evaluation, which was performed to reveal the underlying cause, to have Brugada type 2 syndrome that might be associated with sudden cardiac death. Underlying causes should be evaluated, although idiopathic VTs generally have a good prognosis.

Kurt et al. (2022) conducted a case report in Left posterior fascicular ventricular tachycardia and Brugada type 2 syndrome (n=1). Electrophysiological studies and genetic evaluation was evaluated on Diagnosis of underlying cause of tachycardia. Advanced electrophysiological studies and genetic evaluation in a 13-year-old male with tachycardia attacks revealed left posterior fascicular ventricular tachycardia and Brugada type 2 syndrome.
