心脏猝死是临床和病理学的难题。病理检查通常避开了解剖与临床关联的许多复杂问题。目前,临床和病理关联中的许多复杂问题已迫使我们用较可靠的方法来进行研究。除个别报道外,过去极少注意到心脏自主神经的病理学。这个与严重心律失常有关的问题极为重要;但这方面的研究落后于相应的生理学知识。例如,在高度折返性快速心律失常中,关于双重通道或隐匿性房室传导缺乏组织学方面的依据;心脏神经病理的知识也很贫乏;此外,冠状动脉痉挛在致死性 Sudden cardiac death is a clinical and pathological problem. Pathology often avoids many of the complex issues of anatomy and clinical relevance. At present, many complex issues in clinical and pathological relationships have forced us to study in more reliable ways. Except for individual reports, the pathology of the autonomic nervous system in the heart has rarely been noticed in the past. This issue of serious arrhythmia is extremely important; however, research in this area lags behind the corresponding knowledge of physiology. For example, in patients with highly reentrant tachyarrhythmia, there is a lack of histological evidence of double-channel or occult AV conduction; knowledge of cardiac neuropathies is poor; and coronary artery spasms are fatal
