延边半细毛羊心电图正常值的测定

本实验通过４９例健康延边半细毛羊心电图的描记，初步测定出其正常值。测定的结果表明；心电图为窦性心律，平均心率为１０２次／分；Ｐ波振幅平均为０．０５８ｍＶ，眼限平均为０．０３７秒；Ｐ—Ｒ间期平均为０．１１６秒；ＱＲＳ波群里多种波型，其中以ｑＲ、Ｑｒ、ｑＲｓ和ｒＳ型为最多，时限平均为０．０３９秒；Ｓ—Ｔ段平稳，时限平均为０．１９６秒；Ｔ波振幅平均为０．０８２ｍＶ，时限平均为０．０６５秒；Ｑ—Ｔ间期平均为０．２９５秒。此测定，为心电图应用于诊断延边半细毛羊心脏疾病提供了一定的科学依据。

Determinations of The Electrocardiogram Normal Value of Yanbian Hulf Thin Hair Sheep

After the electrocardiograms of 49 cases of healthy Yanbian half thin hair sheep weretraced, its normal values were determined preliminary. Results showed that the electrocardiogram was sinus,its average heart rate was 102 times per minute ; The amplitude of P wave was averagely 0. 058 mV, the timelimit was averagely 0. 037 second, and the part from P to R was averagely 0. 116 second ; QRS wave groupappeared many kinds of wave modes, and the majority of them belonged to the type of qR. QR, qRs, and rS,the time limit was averagely 0. 039 second ;The part from S to T was smooth, the time limit was averagely0.196 second, The amplitude of T wave was averagely 0. 082 mV, the time limit was averagely 0.065 second; and the part from Q to T was averagely 0. 295 second. This determinations provide certain scientific basis for using electrocardiogram to diagnose the heart diseases of Yanbian half thin hair sheep.
