摘要
本文论述了对生活在海拔3200米高原上120只海晏县藏羊心电图的研究结果。试验中描记并分析了40只1—2月龄羔羊标准肢导联(Ⅰ、Ⅱ、Ⅲ),加压单极肢导联(aVR、aVL、aVF)、双极胸导联(CⅠ、CⅡ、CⅢ)和A—B导联共10个导联的心电图。对80只成年羊还描记和分析了3个单极胸导联(V_1、V_2、V_3)心电图。结果发现被检藏羊皆为窦性心律,心电轴极度右偏(成羊组为149.5°、羔羊组为183.1°)。窦性心律不齐的总发生率为12.6%(成羊组15.0%,羔羊组7.5%)。同时讨论了海晏藏羊心电图的年龄差异、性别差异以及与生活在海拔4000米高原的达日藏羊心电图各项参数的异同。
This paper deals with a result of the study on the electrocardiograms (ECGs) of 120 Tibetan-sheep living at an altitude of 3200 meters above sea level in Haiyan County in Qinghai province. In this experiment, the ECGs were traced and analysed from 11 leads in total which included standard limb leads(Ⅰ, Ⅱ, Ⅲ), augment unipolar limb leads(aVR, aVL, aVF), bipolar chest leads(CⅠ, CⅡ, CⅢ)and apex-base lead (A—B), in 40 Tibetan lambs, the ECGs were also traced and analyced from unipolar chest leads(V_1, V_2, V_3)apartfrom mentioned leads. The results obtained showed that all Tibetan-sheep examined presented a sinus rhythm and that average axis of ECG complex was significantly rightward, which was 149.8° and 183.1° on the ECGs in adult and lamb groups, resp. and that the frequency of sinus arrhythmia in the all Tibetan-sheep, adult and lamb groups was 12.6, 15.0 and 7.5 Per centum, resp. In addition, difference associated with age and sex on the ECGs of the Tibetansheep in Haiyan County was also discussed, and each ECGs parameter of it was compared with those of the Tibetan-sheep living at an altitude of 4000 metres above sea level in Dari County.
