Cardioneuroablation for the Treatment of Vagal Mediated Ventricular Fibrillation in Short QT Syndrome, Case Report.

Augmented vagal effect may be the trigger of ventricular arrhythmia in Short QT syndrome (SQTS). We offer a novel option for refractory cases. This is a 28-year-old male patient who experienced recurrent ICD shocks due to ventricular fibrillation (VF) episodes preceded by enhanced vagal tone. Conventional treatment failed to suppress ventricular arrhythmia. Cardioneuroablation was performed to attenuate vagal response, which ultimately suppressed ventricular arrhythmia. Cardioneuroablation may be an alternative option for vagal mediated ventricular arrhythmia in patients with SQTS refractory to conventional treatments.
