Answer

Some investigators use an electrophysiologic study (EPS) to determine the inducibility of arrhythmias, in an effort to risk-stratify patients with Brugada syndrome. However, the predictive value of this approach is debated. In 2001, Brugada showed that inducibility may be a good predictor of outcome. [36] However, in 2002, Priori reported a poor predictive value of invasive testing. [37] A subsequent study by Gehi concluded that EPS was not of use in guiding the management of patients with Brugada syndrome. [38]
