将狗背位固定在狗台上(即取仰卧位置)。肢体放置电极处,先经剃毛,如用脱毛剂,需在炎症反应消失后一段时间进行记录。标准导联,加压肢体导联和心前导联的连接方法,电极安放位置与人相同,只是一律采用针头电极,所用的20只狗体重在10—20公斤范围内。不同犬心电图的波形及间期可有很大变异,但同一犬不同时间则变异较少,所以最好采用同一犬前后自身对照来分析心电图的变化。
The dog back position fixed on the dog stage (that supine position). Electrodes placed on the limbs, the first by shaving, such as depilatory, to be recorded after a period of time after the inflammatory response disappeared. Standard lead, pressure limb lead and lead connection method, the electrode placement and the same people, but all the needle electrodes, the use of 20 dogs weighing 10-20 kg range. Different dog ECG waveform and interphase may have great variation, but the same dog is less variation at different times, so it is best to use the same dog before and after the self-control analysis of ECG changes.
