摘　　要： 对不同月龄的６６只健康Ｂｅａｇｌｅ犬采用３％戊巴比妥钠麻醉，进行了９个导联的心电图描记和分析。结果表明：健康Ｂｅａｇｌｅ犬为窦性心律：３０月龄以下育成犬心律平均为１７３．８次／分，种用犬（５０月龄以上）心率平均为１３１．７次／分；二者经统计学处理，有极显著差异。Ｐ波间期平均为０．０５１±０．０１３Ｓｅｃ。Ｐ波振幅平均０．０６１ｍｖ，Ｐ波直立在导联中占９２．６％，在ａＶＲ导联中Ｐ波倒置率９８．７５％；ＱＲＳ波间期均值为：０．０２７±０．００５Ｓｅｃ。在Ⅱ导联中范围为０．０２－０．０４Ｓ－ｅｃ。在各导联中，Ⅰ导联以ｒ波为主（５１．８５％），Ⅱ导联以Ｒｓ波多见（５０％），Ｑｒ波和ｑｒ波在ａＶＲ导联中出现较多（３８．８９％，３１．４８％）。Ｔ波在Ⅰ、Ⅱ、Ⅲ、ａｖＦ、Ⅴ１、Ⅴ２、Ⅴ３导联中直立为主，在ａｖＬ导联中倒置多见（８９．２％，７３．１％）。Ｔ波方向与ＱＲＳ波一致。Ｔ波振幅平沟０．１３７ｍｖ。Ｐ－Ｒ间期范围在此０。０７５－０．１４０Ｓｅｃ。在９个导联中，无明显Ｓ－Ｐ段偏移。Ｐ－Ｐ间隔＜０．０１Ｓｅｃ。 : By anaesthesia on 66 varlous month-old healthy Beagle dogs with 3 percent pe-ntboarbital sodium,9-1inked cardiongraphy and analysis were committed.The results indicated : healthy Beagle dog took sinus cadiac rhythm: the rate of brough-up dogsjunior to 30 month old averaged 173. 8 per minute. Dogs kept for covering(senior to 50 month-old) 131.7per minute. Dealing with the two statistically, extremely obvious discrepancy was found between them.Wave Pintervals averaged 0.051 ±0. 013 second, the vibrating extent of wave P averaged 0.061mv.In linkage Ⅱ. straightstanding wave P took 92. 6percent, in linkage a V Rinverting wave P took 98.75percentl; intervals of wave QRS averaged 0.27 ± 0.005 second and ranged from 0.02 to 0.04 second in linkage,Ⅱ. In .all linkages, wave r took the leading role in Ⅰ(51. 85 percent), Rs inⅡ (50 percent),Qr and qr in aVR (39.89 percent and 31.48 percent). Wave T stood straight mostly in linkage Ⅰ.Ⅱ.Ⅲ. aVF. Vl. V2.V3 while inverted mostly in aVL(89.2 percent and 73.1 percent).wave T took the same direction with QRS. The vibrating extentof T averaged 0.137mv. The intervals of P-R ranged from 0.075 to 0.140 second. NO obvious drifting of segment of S-Twas found in the 9 linkages. The intervals of P-P were below 0.01 second.
