本刊现将尹炳生等所著“胸肢导联就是CR导联”和张淑玉等所写“再与头胸导联商榷”两篇文章在此一并刊出,供读者阅读。在我们看来,尹文指出“胸肢导联就是CR导联”及“胸肢导联的右上肢导联不等于VR”等问题是有道理的;而张文则提出“尹文的头胸导联与胸肢导联并无本质差别,”和其它一些问题,双方也各有见解。一般而论,头胸导联是两个电极,其心电图记录反映两个电极处的电位差,广义上来讲,也是双极导联。要达到“单极导联”的要求,应该是负极处的电位总是0,这样正极就能作为探查电极。作者对导联的设计有数学物理的理论作根据,最好再加实验验证、阐明,使理论符合实际情况,欢迎理论工作者与生物工程学工作者深入讨论。 This issue appears Yin Bingsheng other books such as “lead is the CR and CRY” and Zhang Shuyu wrote “again with the lead chest lead discussion,” two articles published in this for readers to read. In our opinion, Yin Wen pointed out that “the lead of the thoracic cords is the CR lead” and “the lead of the right upper extremities of the lead of the thoracic cords does not equal VR.” Zhang Wen made the remark that “Yin Wen’s head There is no essential difference between the lead of the chest and the leads of the thoracic limbs. ”As with other issues, both sides also have their own opinions. In general, the head and chest lead is two electrodes, the ECG records reflect the potential difference between the two electrodes, in broad terms, is also a bipolar lead. To achieve the “unipolar lead” requirement, the potential at the negative should always be zero so that the positive electrode can serve as the probing electrode. The author of the lead on the design of mathematical physics theory as the basis, it is best to add experimental verification, clarify that the theory in line with the actual situation, welcome to the theoretical workers and bioengineers in-depth discussion.
