心电心音同步分析-案例:原型设计三
1️⃣ 标准多模态架构双输入流ECG PCG各自独立编码ECG → 1D CNN EncoderPCG → 1D CNN Encoder中间Multimodal Feature Fusion多模态融合 对应关键词multimodal learning / cross-modal fusion2️⃣ Transformer Attention当前主流你这张图已经体现了两个关键点Self-AttentionTransformer Layers 可以这样写方法“We employ a Transformer-based temporal modeling module to capture long-range dependencies…”3️⃣ 时序建模非常关键Temporal Context时间上下文ECG-PCG同步序列输入 这是你区别传统方法的核心不仅融合模态还建模时间关系4️⃣ 任务输出设计输出包含NormalArrhythmia心律失常Heart Murmur心脏杂音 可以写成“multi-class cardiac condition classification”5️⃣ 训练机制完整Loss Function损失函数Embedding表示 可以补一句“end-to-end trainable framework” 推荐三张图结构非常标准你现在已经有✅ Fig.1 系统框图你前一张 整体系统✅ Fig.2 模型结构图这一张 深度学习方法 建议再补 Fig.3 时间同步机制图内容R-peak vs S1/S2 对齐延迟计算Electromechanical Delay方法描述你可以直接放在 Method 里We propose a multimodal deep learning framework for synchronous ECG and PCG analysis. The model consists of dual-stream encoders for modality-specific feature extraction, followed by a cross-modal fusion module. A Transformer-based temporal modeling block is employed to capture long-range dependencies and electromechanical coupling between cardiac electrical and acoustic activities. The fused representations are then used for multi-class cardiac condition classification in an end-to-end manner.
