Correlation study of electrocardiography and risk stratification in patients with early repolarization syndrome / 中国医师进修杂志

Objective To explore the value of electrocardiagraphy and risk stratification in patients with early repolarization syndrome( ERS ). Methods All of 271 eases were divided into three groups: 7 ERS patients with cardiac events (syncope,clinical sudden death or incompleted, ventricular fibrillation and induced ventricular fibrillation during electrophysiological), 82 ERS patients without cardiac events, and 182 cases without heart disease who were matched for age and sex. QRS interval,Tpeak-Tend (TpTe) interval,corrected QT interval(QTc) and QT deviation degree (QTd) in surface ECG were compared among the three groups. Results TpTe interval in ERS patients with cardiac events was significantly longer than that in ERS patients without cardiac events and the control subjects [ ( 123.3±22.4 ) ms vs (87.7±15.5 ) ms; ( 123.3±22.4) ms vs (83.5±15.1 ) ms, P < 0.05 ]. There was no significant difference in QRS interval, QTc and QTd among three groups. Conclusion TpTe interval in ECG might be useful in risk stratification with ERS, but further research is needed.
