Electrophysiologic study may be helpful in the diagnosis of Brugada syndrome. Some groups have advocated that programmed electrical stimulation (PES) be performed to induce ventricular fibrillation for risk assessment in Brugada patients other groups have not reproduced the predictive value of these tests, so the value of programmed electrical stimulation (PES) and inducibility remains controversial.
