在测定实验狗对直流电的经胸阻抗中,作者发现在连续10次经胸壁直流电电击后,心电图 ST 段抬高及肉眼心肌损伤颇为常见。心肌坏死程度不但与放电能量有关,还受电极板大小及放电间隔时间的影响。为证实上述初步观察,作了以下的实验。方法:将体重14.2～27公斤的狗42只分为7组,每组6只。所有狗均以戍巴比土
In determining the transthoracic impedance of experimental dogs to DC, the authors found that ST-segment elevation and macroscopic myocardial damage were common after 10 consecutive chest wall DC shocks. The degree of myocardial necrosis is not only related to the discharge energy but also affected by the size of the electrode plate and the discharge interval time. In order to confirm the above preliminary observation, the following experiment was made. Methods: 42 dogs weighing 14.2-27 kg were divided into 7 groups with 6 rats in each group. All dogs are garrison Barbie soil
