fQRS被视为心肌瘢痕的标记，心肌纤维化导致心肌动作电位的缓慢和不均一。心电图T波峰末间期（Tp-e间期）代表心室复极化离散，被公认为反映跨室壁离散度的诊断性指标。缺血性J波是由心肌缺血损伤导致的瞬时外向钾离子流（Ito）增强引起。上述可作为恶性室性心律失常及心脏性猝死的高危预警指标。相关研究综述如下。
fQRS被視為心肌瘢痕的標記，心肌纖維化導緻心肌動作電位的緩慢和不均一。心電圖T波峰末間期（Tp-e間期）代錶心室複極化離散，被公認為反映跨室壁離散度的診斷性指標。缺血性J波是由心肌缺血損傷導緻的瞬時外嚮鉀離子流（Ito）增彊引起。上述可作為噁性室性心律失常及心髒性猝死的高危預警指標。相關研究綜述如下。

Fragmented QRS complex has been regarded as marker of myocardial scar.Myocardial fibrosis causes slow and inhomoge-neous activation.The interval between Tpeak and Tend,a novel marker of heterogeneity of ventricular repolarization,has been recognized as a surrogate diagnostic parameter of transmural dispersion of repolarization.Ischemic J-wave results from increased Ito of cardiac is-chemic.This markers may serve as high-risk warning of malignant ventricular arrhythmia and sudden cardiac death.So a review is made on correlative research in recent years.
