SNE是一种新近出现的直接记录窦房结电活动的方法。将之用于评价SN功能较传统的间接方法更为真实可靠。近来,SNE技术已由心内记录法发展到食道和体表无创记录法,并初步应用于临床。同时,有部分学者对现行SNE技术提出异议,认为所报导的SNE多有伪差。因而,如何进一步改进记录方法,去伪存真仍是目前SNE领域的研究课题。
SNE is a newly emerging method of recording the electrical activity of the sinoatrial node directly. It is more realistic and reliable to evaluate SN functions than traditional indirect methods. Recently, SNE technology has been developed from the intracardiac recording method to non-invasive esophageal and body surface recording method, and initially applied to clinical. At the same time, some scholars have raised objections to the current SNE technology. They think there are many false positives in the reported SNEs. Therefore, how to further improve the recording method and go false or not is still the research topic in the field of SNE.
