目前国内外人群中各种疾病的发病率,都以心血管疾病占首位,心血管生理及治疗心血管疾病药物的研究日显重要。犬是常用的实验动物。心电图是反映心脏活动的重要指标。对犬正常心电图的研究虽有很长历史,但国内缺乏这方面的系统研究。本工作记录了犬的标准导联、加压肢体导联及胸前导联的心电图的统计比较,为有关科研工作提供参考数据。方法体重11～13公斤健康草种犬40条,性别不拘,每天上午8～9时空腹,经训练后,在立位清醒下描记:标准肢体导联Ⅰ、Ⅱ、Ⅲ,单极加压肢体导联aVR、aVL、aVF及单极胸前导联V_5等7个导联的心电图。用针电极插入皮下进行引导。用上海医
At present, the prevalence of various diseases in the population both at home and abroad is dominated by cardiovascular diseases, and research on cardiovascular physiology and drugs for treating cardiovascular diseases is increasingly important. Dogs are commonly used laboratory animals. ECG is an important indicator of heart activity. Although there is a long history of the study of dogs normal ECG, but the lack of systematic research in this area. This work records the dog’s standard lead, compression limb lead and chest lead ECG statistics comparison, provide reference data for scientific research. Methods Weighed dogs (weighing 11 ~ 13 kg) had 40 healthy grass breeds. Their sex was not different. They were fasted from 8 to 9 am every day. After training, they were traced under awake position: standard limb leads Ⅰ, Ⅱ and Ⅲ, unipolar compression limbs Lead aVR, aVL, aVF and unipolar chest lead V_5 and other seven lead ECG. Use the needle electrode to insert into the skin for guidance. Shanghai Medical
