EPHNOGRAM: A Simultaneous Electrocardiogram and Phonocardiogram Database

The electro-phono-cardiogram (EPHNOGRAM) project focused on the development of
low-cost and low-power devices for recording simultaneous electrocardiogram
(ECG) and phonocardiogram (ECG) data, with auxiliary channels for capturing
environmental audio noise, which could be used for PCG quality enhancement
through signal processing. The current database, recorded by version 2.1 of
the developed hardware, has been acquired from 24 healthy adults aged between
23 and 29 (average: 25.4 ± 1.9 years) in 30min stress-test sessions during
resting, walking, running and biking conditions, using indoor fitness center
equipment. The dataset also contains several 30s sample records acquired
during rest conditions. This data is useful for simultaneous multi-modal
analysis of ECG and PCG. It provides interesting insights into the inter-
relationship between the mechanical and electrical mechanisms of the heart,
under rest and physical activity.

本心电心音图（electro-phono-cardiogram, EPHNOGRAM）项目聚焦于研发低成本、低功耗的采集设备，可同步采集心电图（electrocardiogram, ECG）与心音图（phonocardiogram, PCG）数据，并增设辅助通道采集环境音频噪声，能够通过信号处理技术实现心音信号的质量增强。
本次构建的数据库由该项目研发的2.1版硬件采集完成，采集对象为24名年龄介于23至29岁（平均年龄25.4±1.9岁）的健康成年人，数据采集于室内健身中心，开展了时长30分钟的运动负荷测试，涵盖静息、行走、跑步与骑行四种状态，测试过程使用室内健身器材完成。
该数据集还包含若干条静息状态下采集的30秒样本记录。
此数据集可用于心电图与心音图的多模态同步分析，能够为探究静息与体力活动状态下心脏机械活动与电活动机制之间的内在关联提供有价值的研究视角。
