Abstract: Objective To explore the predictive value of ventricle late potential (LP) for arrhythmic events in the patients with Brugada syndrome. Methods Totally 43 patients with Brugada syndrome were divided into symptom group (n=24) and asymptom group (n=19).Signalaveraged electrocardiography(SAECG) was performed to analyze characteristics of LP in all subjects.The occurrence of arrhythmic events was observed in all patients during the dynamic follow-up for (33.8±9.0) months.Results There were 22 cases (91.7％) and 7 cases (36.8％) with LP positive in patients with symptom and asymptom,respectively.The incidences of arrhythmic events were 72.4％ in Brugada syndrome patients with positive LP and 14.3％ in patients with negative LP,respectively.The relative risk (RR,95％ CI) for LP prediction of the arrhythmic events was [5.1,(1.4～ 18.6)] (P =0.002). ConclusionsLP may be one of effective factors predicting arrhythmic events in the patients with Brugada syndrome.
