[Concurrent long QT and Brugada syndrome in a single patient].
We present a 61-year-old patient with previous cardiac arrest and frequent syncopal spells. ECG showed a typical Brugada pattern and a QTc interval of 425 ms. During programmed ventricular stimulation a self-limited syncopal polymorphic ventricular tachycardia was induced. On diagnosis of the Brugada syndrome an implantable cardioverter defibrillator was implanted. Two days later two episodes of polimorphic ventricular arrhythmia were converted by the device. The ECG at this time showed a prolonged QTc of 500 ms in addition to a typical Brugada pattern. Atenolol was started and after a 36-month follow-up the patient has remained asymptomatic without arrhythmic events. In conclusion, this patient has the Brugada syndrome and also fulfills the clinical and ECG characteristics of the Long QT syndrome. These findings suggest a genetic link between the two syndromes.
