摘　　要：碎裂QRS是指碎裂QRS两个连续导联呈RSR’型(≥1个R’波、R波或S波存在切迹),但并无典型束支传导阻滞的心电图图形。碎裂QRS可能是一种特殊类型的心肌梗死,是心脏事件的预测因子和心肌瘢痕的标志,也是室壁瘤的标志。QRS complex fragmentation （fQRS）, is defined as changes in QRS morphology （ 〈 120 ms） with different RSR＇patterns, 〉 1 R ＇wave, notched R wave, or notched S wave, which do not related to right bundle branch block. Prognostic significance of QRS predicts the risk of recurrent cardiac events in patients with myocardial infarction, and diagnostic value as a sign of myocardial infarction scaring. It is also a sign of left ventricular aneurysm.
