Therefore, in this study, we propose a three-level risk stratification algorithm for arrhythmia, which not only ensures precise intervention for different types of arrhythmias to achieve optimized allocation of medical resources but also comprehensively captures the spatiotemporal features of ECG signals for high-accuracy risk stratification detection. The algorithm first proposes a three-level arrhythmia risk stratification scheme, classifying cases as Normal, Not Life-threatening, and Life-threatening, with corresponding intervention measures of no need for monitoring, close attention, and immediate intervention, respectively. The core model of this algorithm is a deep learning fusion network based on the palindromic structure of Convolutional Neural Network (CNN) and Long Short-Term Memory network (LSTM), which enables precise three-level risk detection for all types of arrhythmias. Experimental results demonstrate that the algorithm exhibits favorable generalization performance across multiple datasets.

The ECG-respiration fusion model achieved an accuracy of 0.814, a recall of 0.749, a precision of 0.635, an F1-score of 0.680, an area under the receiver operating characteristic curve (AUROC) of 0.863, and an area under the precision-recall curve (AUPRC) of 0.675, outperforming both TTAS and single-modality models. Ablation analyses confirmed the additive value of spatial attention and class-balanced loss. Score-CAM visualizations indicated the model focused on physiologically relevant features, such as respiratory waveform inflection points.</p><p><strong>Conclusions: </strong>A multimodal deep learning approach combining ECG and respiration video signals can predict hospital admission at ED triage. Integrating such models into triage systems may enhance earlier risk identification and resource prioritization.</p><p><strong>Clinical trial number: </strong>Not applicable.</p>","PeriodicalId":48947,"journal":{"name":"Biodata Mining","volume":" ","pages":""},"PeriodicalIF":7.9,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13563894/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148413420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
