在心血管电生理及药理学研究中常以狗为实验对象,体表心电图的变化虽是常用指标,但它测不出房室结和希氏束浦顷野系统的电活动。近年来发展较快的希氏束电图则弥补了这一不足。国内外对正常狗希氏束电图的记录曾有报道,但迄今为止,对于较大系列健康狗希氏束电图正常时值的研究,尚未见论述。现将正常成年杂交狗希氏束电图报道如下。 In the electrophysiological and pharmacological studies of dogs, dogs are often used as experimental subjects. Although the changes of body surface electrocardiogram are commonly used indicators, they can not detect the electrical activity of the atrioventricular node and His bundle system. In recent years, the rapid development of His harness beam make up for this shortcoming. At home and abroad, the records of normal dogs Hisxograph have been reported, but up to now, there is no discussion on the normal values ​​of the larger series of healthy Hischospheres. The normal adult hybrid dog His sonogram is reported below.
