急诊心电图识别精要(PPT)

急诊心电图识别精要（PPT）

以下19种心电图建议从事院前急救专业的医务人员熟练识记：

房性早搏/室性早搏，房扑/房颤，室扑/室颤，室速/室上速/尖端扭转型室速,二度二型房室传导阻滞/三度房室传导阻滞，窦性静止/心电静止/无脉电活动，前壁/下壁/后壁心肌梗死，低钾血症/高钾血症。

  • 心电图正常不能排除心脏病。

  • 心电图的正常范围较大，判定标准不是绝对的，应避免将一些正常变异误认为不正常，如T波的改变就很不稳定。

  • 心电图的某些改变并不具有特异性，同样的心电图改变可见于多种心脏病，对其判断必须结合临床。

  • 心电图不能对心脏的收缩功能、瓣膜损害等情况作出判断，不能作为心脏功能的判断依据。
