The Shanghai Score System, which weighs electrocardiogram (ECG) findings reflecting repolarization abnormalities, has been proposed for diagnosis of early repolarization syndrome (ERS). However, recent studies have suggested the involvement of depolarization abnormalities in some ERS patients. The aim of this study was to validate the Shanghai Score System in predicting the recurrence of ventricular fibrillation (VF) in ERS patients. The predictive value of fragmented QRS (fQRS) was also investigated.

碎裂QRS波及上海评分系统在早期复极综合征患者心室颤动复发中的作用

上海评分系统对反映复极异常的心电图 (ECG) 结果进行权衡，已被提议用于早期复极综合征 (ERS) 的诊断。然而，最近的研究表明一些 ERS ​​患者存在去极化异常。本研究的目的是验证上海评分系统在预测 ERS ​​患者心室颤动 (VF) 复发方面的作用。还研究了碎裂 QRS (fQRS) 的预测价值。
