猝死综合症用来泛指急死后是用传统检查技术手段未能发现致死病变的情况。由于原因不明,其诊断和病因学的研究均十分困难。猝死综合症的诊断是法医学尸体检验实践中的难题之一。近年来,随着分子生物学技术和遗传学研究的不断深入,对于一些与猝死有关的发现不断报道,有希望用于法医学实践,用于将此类猝死进一步分型,并为进一步的深入研究提供准确的流行病学资料。 Sudden death syndrome is used to refer to the case of acute death is not detected by conventional means of detection of lethal lesions. Due to unknown reasons, the diagnosis and etiology of the study are very difficult. Sudden death syndrome diagnosis is one of the problems in the practice of forensic autopsy. In recent years, with the deepening of molecular biology and genetics research, some reports related to sudden death have been reported, promising for forensic practice and further sub-classification for such sudden death, and for further research Provide accurate epidemiological information.
