摘要
参照测定人体心电图的标准Ⅱ导联,研究了鲤、蛙、龟、蛇、鸡、马、驴、西门塔尔牛、湖羊、细毛羊、梅花鹿、驼、猪、犬、猫、小白鼠、家兔和人等五大类17种具有代表意义的动物心电图,对其P波、QRS波、T波的形态学进行了比较分析,其结果表明:鲤、蛇的P波形态变异较大,且鲤P波与人类P波形态相反,有50％呈负向,其余动物的P渡与人类P波的形态相似,呈现以正向为主,鲫、蛙、龟、蛇的QRS波以R波为主波,其中鲤以QR波为主,蛙为RS波,龟、蛇以Rs波为主,鸡52％呈RS型,42％呈rS型,其余动物和人类均属于以R波为主的QRS波,同一种动物的QRS波可有各种形态出现,主要为QR、qR,qRs、Rs,RS、R波的QRS波型,蛙、蛇、猫、兔、猪、驴、驼等动物的T波与人类相似、呈现以直立为主,其他动物的形态则变异较大。
This paper deals with the comparative aspects of electrocardiograms(ECG)representative of 17 different animal species with standard limb lead I as used in the determination of human ECG.Animals involved in the study included carps,frogs,tortoises,snake chicken,horses,donkeys,simmental cattle,Taihu sheep,fine-wool sheep,sika deers,camels,pigs,dogs,cats,mice and rabbits.ECG of the human was used for comparison.Forms of P,QRS and T waves were compared.There were considerable variations in P waves of carps and snakes.The P wave form was different from that of the human,with about 50% of its waves in the negative form,while the remaining animlas showed forms of P waves similar to those of men,mostly with a positive type.The QRS complexes of carps,frogs tortoises and snakes appeared mostly in R-dominated forms.The carps showed the QR domination and the frogs were predominated by the RS type.Tortoises and snakes were marked largely by the Rs complex.In chicken,52% was in RS type and 42%,in rS type.AH the mammalian animals showed the R-dominated QRS complex similar to the human being.The QRS complex in the same animal species might appear in different forms,mostly in forms of OR,qR,qRS,Rs RS and R.Animals Such as frogs,snakes,cats,rabbits,pigs,donkeys,and camels had upright T wave forms like the human,but there were considerable differences in the other animal species.
