摘要 碎裂QRS波(fragmented QRS,fQRS)是新近出现的一项重要的无创心电指标。fQRS形成最重要的机制是心肌瘢痕所致的传导异常,因而最常见于冠心病患者,对陈旧性心肌梗死的诊断具有很高的敏感性,远高于病理性Q波,对冠心病患者的死亡率和心血管事件的发生率有很好的预测价值。除见于冠心病外,fQRS也见于其他能导致心肌传导异常的疾病,如Brugada综合征、心肌病、心肌炎、瓣膜性心脏病等。fQRS与室性心律失常关系密切,它对缺血性心肌病和Brugada综合征等患者室性心律失常的发生具有较高的预测价值,对这些患者的死亡率也有一定的预测价值。因此,fQRS是判断心脏病患者预后的一项重要指标。
