目的 探讨心电图对早期复极综合征(ERS)危险分层的价值.方法 将7例有心脏事件(晕厥、猝死及猝死未遂、临床记录心室颤动、电生理诱发心室颤动)的ERS患者、82例无心脏事件的ERS患者及182例健康对照者的心电图QRS时限、T波峰.末间期(TpTe)、校正QT间期(QTc)及QT离散度(QTd)进行比较. 结果有心脏事件的ERS患者、无心脏事件的ERS患者和健康对照者的TpTe分别为(123.3 ±22.4)、(87.7 ±15.5)、(83.5±15.1)ms,有心脏事件的ERS患者TpTe与无心脏事件的ERS患者及健康对照者比较差异均有统计学意义(P0.05).结论 心电图中TpTe可能对ERS患者危险分层有一定价值,但尚需进一步研究证实.“,”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 rnpatients 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.
