左主干病变(LMCA)是冠心病的严重类型,特别是以LMCA为罪犯病变的急性冠脉综合征(ACS)可导致患者血流动力学迅速恶化,发生心源性休克和恶性心律失常。因此,早期识别LMCA病变非常重要。
最近遇到一例疑似LMCA急性闭塞的患者,可惜没有上台的机会。结合文献再复习下LMCA病变的心电图表现。

左主干病变心电图表现
左主干病变根据是否闭塞,分为严重狭窄(次全闭塞)或急性完全闭塞,他们的心电图心电图表现形式是不同的。
LMCA的心电图没有固定的表现形式,往往呈现多样性。
左主干严重狭窄的心电图改变
左主干急性完全闭塞心电图
左主干病变心电图分型
最后,对LMCA的心电图表现进行总结:在看心电图的时候一定不要忽视患者临床表现,LMCA急性闭塞或次全闭塞是非常严重的冠心病类型,多数会伴有心源性休克!
