病例分享:地高辛中毒?心电图里有玄机!

2018-03-07 江苏省人民医院 卢妙 许迪 黄元铸 中国医学论坛报今日循环

1例72岁男性患者,有慢性心房颤动(房颤)病史,长期口服地高辛,主诉虚弱、恶心、呕吐。

1例72岁男性患者,有慢性心房颤动(房颤)病史,长期口服地高辛,主诉虚弱、恶心、呕吐。



心电图诊断1. 房颤心律;2. 交界性逸搏心律;3. 心率49次/分;4. 三度房室传导阻滞。

评述

1. 患者基础心律为心房纤颤,在几个导联中可以明显看出,这些导联表现为细微、低振幅的纤颤波。患者以前的慢性心房颤动病史也支持这一点。

2. 心房颤动通常表现为心律绝对不齐,然而,该患者的心室律是规则的。只有当心房纤颤波被完全阻断而无法传导至心室(比如地高辛中毒导致三度房室传导阻滞)时才会出现这一现象。取而代之的是,房室交界处或心室成为新的起搏点。该患者为规则的窄QRS波群,心率为49次/分,提示交界性逸搏心律。

3. 该心电图ST段压低呈“鱼钩样”改变,也有人描述心电图中缓慢下降的R波与T波共同构成“曲棍球”样。这一表现通常与使用地高辛有关,被称为“地高辛效应”。

4. 该心电图有上述几种特征,将这些特征结合在一起应考虑地高辛中毒。

5. 临床上若怀疑患者地高辛中毒时,应检测患者血清地高辛浓度。该患者血清地高辛浓度为5.1 ng/ml(正常0.5~2.2 ng/ml)。
