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.

该电声心动图（EPHNOGRAM）项目致力于开发低成本、低功耗的设备，用于同时记录心电图（ECG）和心音图（PCG）数据，并附带用于捕捉环境音频噪声的辅助通道，这些通道可通过信号处理技术用于PCG质量提升。当前数据库由所开发硬件的2.1版本记录，数据来源于23至29岁（平均：25.4 ± 1.9岁）的24名健康成人，在休息、行走、跑步和骑自行车等条件下的30分钟压力测试期间获取。数据集还包含在休息条件下获得的数个30秒样本记录。该数据对于心电图和心音图的同步多模态分析极为有用，它揭示了心脏机械与电生理机制在休息与物理活动状态下的相互关系，提供了引人入胜的见解。
