本文报道50例狗立位时的正常心电图。结果如下:心率130.340±3.937次/分,40％的狗出现窦性心率不齐,98％的QRS波平均心电轴位于0～90°之间,QRS波时间为0.052±0.001秒。对各波段的波形、时间、振幅进行了分析,提出用网兜状狗架固定实验用狗使之取立位状态描记心电图的可行性。
This article reports the 50 cases of normal standing when the dog’s ECG. The results were as follows: Heart rate was 130.340 ± 3.937 beats / min. The sinus arrhythmia was observed in 40% of the dogs. 98% of the QRS waves had an average ECG axis between 0 ° and 90 ° and the QRS wave time was 0.052 ± 0.001 seconds. The waveforms, time and amplitude of each band were analyzed, and the feasibility of using the dog-shaped frame to fix the experimental dog to take the standing state of the electrocardiogram was proposed.
