基于多模态生理信号融合的猝死风险实时评估系统及方法

本发明公开了一种基于多模态生理信号融合的猝死风险实时评估系统及方法，涉及人体生理状态监测与预警领域，解决了单模态信号评估猝死风险准确性低、实时性差的问题。该系统含信号采集、预处理、高维特征提取、多模态特征融合、猝死风险量化、模型更新引擎及预警反馈模块，各模块集成自适应滤波、时序卷积网络、改进多头自注意力机制等单元。方案通过多通道同步采集心电等多模态信号，经自适应降噪、时频域非线性特征并行提取、互信息加权融合，结合核密度估计计算动态风险指数，实现模型在线增量更新与多级预警；可实时、精准评估猝死风险，提升异常检测灵敏度与预警时效性，适用于日常健康监测及高危人群风险管控。
