远东刺猬正常心电图的描记

Electrocardiogram in Normal Amur Hedgehog (Erinaceus amurensis)

本文采用标准双极导联(Ⅰ、Ⅱ、Ⅲ)和加压单极肢导联(aVR、aVL、aVF)对12只成体远东刺猬Erinaceus amurensis进行心电图测定。结果表明,远东刺猬的平均心率为294±46次/min,均为窦性心律。各导联的波形均较规则而稳定,所有导联都有QRS波群和T波,P波只在导联Ⅰ、Ⅱ、aVF中较明显,R′波明显存在于导联Ⅲ中。

The electrocardiogram of 12 Erinaceus amurensis was studied.Leading methods included standard limb lead(Ⅰ,Ⅱ,Ⅲ) and the augmented limb leads(aVR,aVF,aVL).The results are as follows: the mean heart rate of Erinaceus amurensis was 294±46/min,and a sinus rhythm was shown in all hedgehogs.The waves of all the limb leads were regular and stable.There were QRS wave and T wave in all limb leads,but P wave only evidently lie in limb lead(Ⅰ、Ⅱ、aVF) and R′ wave only in limb lead Ⅲ.
