Atypical Cause of Syncope in Patients with Brugada Syndrome

Four months later, the patient was admitted to the emergency room 24 hours after having had a new syncopal episode. The syncope occurred during a party where the patient took alcohol and drugs (cannabis and cocaine). The device was checked and a progressive sinus bradycardia, followed by a 4.5 seconds sinus arrest were evidenced (Figure 2) at the time of the syncope. The patient was discharged with the following diagnosis: neurocardiogenic syncope and secondary bradicardia/sinus arrest. No other syncopes or further brady-tachyarrhythmias were recorded during the 15 months of device duration, which was finally explanted. The patient remains alive and visits the clinic regularly.
