碎裂QRS波在急性心肌梗死患者诊断及预后中的应用价值评价(1)
[摘要] 目的 探究碎裂QRS波在急性心肌梗死患者诊断及预后中的应用价值。方法 整群选取2014年11月—2016年1月在该院心内科就诊的248例冠心病患者。按是否为AMI分为两组各124例。比较不同心电图指标在AMI中的诊断价值,并记录不同心电图病理波形者发生的并发症及心源性死亡的发生率。結果fQRS波合并病理性Q波敏感度为36.29%,特异性为96.77%,阳性预测值为91.83%,高于单纯fQRS波、单纯病理性Q波。此外,有fQRS波的患者77例,严重并发症发生率为53.25%,心功能不全发生率为49.35%,死亡发生率为19.48%。与无fQRS波患者存在显著性差异。结论 fQRS波用于AMI早期诊断可靠性高,灵敏度好、特异性强,具有临床推广价值。
