摘要:
脉冲波形图(PPG)是一种广泛使用的非侵入式传感模态,用于连续的心血管和生理监测,在临床、实验室和可穿戴设备中均有应用。尽管现有PPG数据集支持广泛的任务,但它们通常以数值测量或任务特定标签的形式提供监督,限制了其与基于语言的接口和多模态基础模型的兼容性。在本工作中,我们介绍了PulseLM,一个大规模的PPG-文本问答数据集,通过统一的问答(QA)框架将原始PPG波形与自然语言连接起来。PulseLM整合了十六个公开可用的数据源中的PPG记录,并将异构标注统一到12个下游任务中。该数据集包含超过100万个标准化的10秒PPG片段,与近250万个问题-答案对相关联。我们进一步定义了可重复的数据管道、训练和评估协议,并通过多模态PPG-aware大语言模型建立了基线基准。PulseLM为研究语言基础生理推断、跨数据集泛化和PPG多模态模型的可扩展基准提供了标准化基础。我们公开发布了数据集和代码,分别在https://huggingface.co/datasets/Manhph2211/PulseLM和https://github.com/manhph2211/PULSE-LM上。
英文摘要:
Photoplethysmography (PPG) is a widely used non-invasive sensing modality for continuous cardiovascular and physiological monitoring across clinical, laboratory, and wearable settings. While existing PPG datasets support a broad range of downstream tasks, they typically provide supervision in the form of numerical measurements or task-specific labels, limiting their compatibility with language-based interfaces and multimodal foundation models. In this work, we introduce PulseLM, a large-scale PPG-text question-answering dataset that bridges raw PPG waveforms and natural language through a unified question-answering (QA) formulation. PulseLM aggregates PPG recordings from sixteen publicly available sources and harmonizes heterogeneous annotations into 12 downstream tasks. The dataset comprises over 1 million standardized 10-second PPG segments, associated with nearly 2.5 million question-answer pairs. We further define reproducible data pipeline, training, and evaluation protocols and establish baseline benchmarks using multimodal PPG-aware large language models. PulseLM provides a standardized foundation for studying language-grounded physiological inference, cross-dataset generalization, and scalable benchmarking of PPG-based multimodal models. We publicly release the dataset and code at https://huggingface.co/datasets/Manhph2211/PulseLM and https://github.com/manhph2211/PULSE-LM, respectively.
