引入青海省民和县小尾寒羊心电图的研究

Study on Electrocardiograms of Little Tail Han Sheep Which were Introduced into Qinghai Province Minhe County

采用6个肢导联和A—B导联对引入青海民和县小尾寒羊的心电图进行了描记和分析,结果:被检羊均为窦性心律;R—R间期为 0.72 ± 0.17s;心电轴为十174.l±58.5°;QRS波在I,aVL导联以QS为主,Ⅱ导联以Qr为主,Ⅲ导联以qR为主,aVR导联以Rs为主,aVF导联以qR和Qr为主,A—B导联均为rS或QS;各波和间期的时限(s)为,P波:0.051±0.016,P—Q间期:0.131±0.023,QRS波:0.054±0.01,T波:0.08±0.015 Q—T间期:0.309±0.036,Q—Tc间期;0.369±0.027;被检羊中心律失常发生率达76.7％.

Electrocardiograms of Little tail Han sheep which were introduced into Qinghai province Minhe county were recorded and analysed from 6 limb and A-B lead. The results were as follows: There was a sinus rhythm in all examined sheep; the R - R interval time was 0.72 ±0.17 (s);the average cardiac axis of QRS complex was + 174.1 ± 58.5°; the QRS complex form was QS in I, aVL leads, and Qr in Ⅱ lead, and qR in Ⅲ lead , and Rs in aVR lead, and qR or Qr in aVF lead primarily, and all of it were rS and QS in A - B lead; the duration(s) of various waves and intervals was;P:0.051± 0.016.P-Q: 0.131 ± 0.023,QRS:0.054 ± 0.01, T:0.08 ± 0.015, Q-T:0.309 ±0.036, Q-Tc:0.369 ±0.027; in examined sheep frequency of cardiac arrhythmia was 76.3 % .
