摘　　要：QRS波群碎裂指QRS波群形态(<120ms)转变为不同的RSR'形式:额外R波、S波切迹或>1个R'波。有关其预后价值的资料很少。本研究拟在350例首发Q波心肌梗死(MI)的患者中,评估Q波和QRS波群碎裂对于再发心脏事件的预测价值;再发心脏事件指心脏性死亡、非致死性MI或不稳定型心绞痛(无论哪一个首先发生)。随访(平均2个月)心电图(ECG)显示,There are limited data regarding the prognostic value of QRS complex fragmentation,defined as changes in QRS morphology(<120 ms) with different RSR′ patterns: additional R waves, notched S wave, or >1 R′ wave. The purpose of our analysis was to assess the prognostic value of presence of Q waves and QRS fragmentation for predicting recurrent cardiac events, defined as cardiac death, nonfatal myocardial infarction(MI), or unstable angina, whichever occurs first, in 350 patients with first Q- wave MI.
