青海本地山羊心电图的研究
Progress in Veterinary Medicine(2004)
Abstract
对29只青海本地山羊标准肢导联(Ⅰ,Ⅱ,Ⅲ)、加压单极肢导联(aVR,aVL,aVF)、单极胸导联(V1~V6)、双极胸导联(一)(C1,C2,C3)和A-B导联共16个导联的心电图进行了分析和研究.结果发现:①平均心电轴显著右偏,为+149.7°±54.9°(-1°~+268.5°);②皆为窦性心律,但窦律不齐出现概率高达89.7%;③P波和T波波向一致性较好的有Ⅰ,Ⅱ,aVF,C1和A-B导联(正向)以及aVR,V3,V4,V5,V6,C2和C3导联(负向);④在Ⅲ,aVF,V3,V4,V5,V6,C2和C3导联心电图上,QRS综合波以qR或R主要波型,而在Ⅰ,aVL,V2,C1和A-B导联心电图上以rS,Qr或QS为主要波型;⑤各波和间期的时限(s)为:P波(0.053±0.021);QRS综合波(0.060±0.017);T波(0.092±0.032);P-Q间期(0.125±0.049);Q-T间期(0.314±0.058);Q-Tc间期(0.346±0.064);R-R间期(0.822±0.174).
