AnxiECG-PPG Database: Synchronized ECG and mobile PPG Signals during Baseline, Physical Activated, and Psychological Activated Conditions

The AnxiECG-PPG Database contains synchronized electrocardiogram (ECG) and mobile-acquired photoplethysmography (PPG) recordings from 47 healthy participants. Moreover, the acquisition protocol assesses three distinct states: a 5-minute Baseline, a 1-minute Physical Activated State, and a Psychological Activated state provoked through emotion-induced videos (negative, positive, and neutral emotion valence). Recordings were conducted at the Institute of Electronics and Informatics Engineering of Aveiro and the Institute of Biophysics and Biomedical Engineering from February to March 2024. The BioSignalPlux Explorer Research Kit captured ECG data, while PPG signals were acquired via smartphone (iPhone 11, Apple U.S.) with the HOLI app by NEVARO Tech. This dataset aims to evaluate PPG's potential in deriving cardiac metrics and its viability as an anxiety biomarker, with a comparative analysis against ECG signal recordings.AnxiECG-PPG数据库包含47名健康受试者的同步心电图（electrocardiogram, ECG）与移动端采集的光电容积描记（photoplethysmography, PPG）记录。该采集方案针对三种不同实验状态开展评估：时长5分钟的静息基线状态、时长1分钟的身体激活状态，以及通过情绪诱导视频（涵盖负性、正性与中性情绪效价）诱发的心理激活状态。数据采集工作于2024年2月至3月间，在阿威罗大学电子与信息工程研究所与生物物理与生物医学工程研究所完成。心电图数据由BioSignalPlux Explorer Research Kit采集，而光电容积描记信号则通过美国苹果公司iPhone 11智能手机，搭载NEVARO Tech开发的HOLI应用程序完成采集。本数据集旨在评估光电容积描记在提取心脏相关指标方面的应用潜力，以及其作为焦虑生物标志物的可行性，并同步开展与心电图信号记录的对比分析。
