    怀孕与未孕乳牛在九种导联心电图的比较

    COMPAR1S1ON OF ECG IN NINE LEADS BETWEEN PREGNANT AND NON-PREGNANT DAIRY COWS

    • 摘要: 用XQ—IA型心电图机(中国上海七一器材厂出品)对52头黑白花乳牛(内39头已孕,13头未孕)进行了心电图测定。测定心电图所用的导联共9个,即分别为:三个标准导联,三个加压肢导联和三个单极心前导联。所得结果如次:1.孕牛与未孕牛的心电轴均有左、右偏移现象;2.孕牛心率则未孕牛稍高,但不显著;3.在标准Ⅱ导联、aVR、aVF三个导联中,孕牛的P波电压比未孕牛者增加,而且在Ⅱ导联和aVR导联中非常明显(P<0.01);4.aVR、aVF的P波时间,孕牛比未孕牛有较明显的延长(0.01
