Abstract:
Objective To study the pathological changes of the sudden death cases due to the dysplasia of the cardiac conduction system. Methods Using the newly established pathological sampling method by our research team, 26 hearts of unidentified sudden deaths excluding trauma, poisoning and diseases were collected and observed optically with H&E staining, Masson staining and immunohistochemical staining. Results Among the 26 cases, there were dysplasia in the cardiac conduction system,structural abnormalities, tissue or structure shift, fibrous cushion in the sinoatrial node and 9 cases have 2~3 abnormalities at the same time. Among the age groups from 16 to 30, 21 cases (80.8%) showed dysplasia of the cardiac conduction system. Conclusion The dysplasia of the cardiac conduction system may be one of the predominant reasons for the sudden death in young adults.
