为了确立房性心律失常与窦房结组织病变之间的关系,作者对111例尸检患者的窦房结进行了连续切片研究。 (1)窦性心律组:60岁以上(36例)与60岁以下(26例)者相比,结细胞的百分率显著减低,纤维化数量则显著较高(P<0.001)。(2)心房颤动和心房扑动组:29例心房颤动或心房扑动患者与58例同一年龄组的窦性心律患者相比,其结细胞的百分率稍低,但差
In order to establish the relationship between atrial arrhythmia and sinus node tissue lesions, the authors performed serial sectioning of the sinus node in 111 autopsy patients. (1) Sinus rhythm group: The percentage of node cells was significantly decreased and the number of fibrosis was significantly higher than that of patients aged 60 years (36 cases) and 60 years of age (26 cases) (P <0.001). (2) atrial fibrillation and atrial flutter group: 29 cases of atrial fibrillation or atrial flutter patients compared with 58 cases of sinus rhythm patients of the same age group, the percentage of node cells was slightly lower, but poor
