MSCardio Seismocardiography Dataset

Overview

The MSCardio Seismocardiography Dataset is an open-access dataset collected as part of the Mississippi State Remote Cardiovascular Monitoring (MSCardio) study. This dataset includes seismocardiogram (SCG) signals recorded from participants using smartphone sensors, enabling scalable, real-world cardiovascular monitoring without requiring specialized equipment. The dataset aims to support research in SCG signal processing, machine learning applications in health monitoring, and cardiovascular assessment.

Background

Cardiovascular diseases remain the leading cause of morbidity and mortality worldwide. SCG is a non-invasive technique that captures chest vibrations induced by cardiac activity and respiration, providing valuable insights into cardiac function. However, the scarcity of open-access SCG datasets has been a significant limitation for research in this field. The MSCardio dataset addresses this gap by providing real-world SCG signals collected via smartphone sensors from a diverse population.

Data Description

Study Population

• Total participants enrolled: 123
• Participants who uploaded data: 108 (46 males, 61 females, 1 unspecified)
• Age range: 18 to 62 years
• Total recordings uploaded: 515
• Unique recordings after duplicate removal: 502
• Platforms used: iOS and Android smartphones

Signal Data

• Axial vibrations in three directions (SCG) recorded using smartphone sensors
• Sampling frequency varies depending on the device capabilities
• Data synchronization is ensured for temporal accuracy
• Missing SCG data identified in certain recordings, addressed through preprocessing

Metadata

Each recording includes:

• Device model (e.g., iPhone Pro Max)
• Recording time (UTC) and time zone
• Platform (iOS or Android)
• General demographic details (gender, race, age, height, weight)

File Structure

The dataset is organized as follows:

MSCardio_SCG_Dataset/

│   │   │   ├── uncalibrated_scg.csv     # Raw SCG signal
│   │   │   ├── recording_metadata.json  # Timestamp and device details

Data Collection Protocol

• Participants placed their smartphone on their chest while lying in a supine position.
• The app recorded SCG signals for approximately two minutes.
• Self-reported demographic data were collected.
• Data were uploaded to the study's cloud storage.

Usage and Applications

This dataset is intended for research in:

• SCG signal processing and feature extraction
• Machine learning applications in cardiovascular monitoring
• Investigating inter- and intra-subject variability in SCG signals
• Remote cardiovascular health assessment
• The Data_visualization.py script is provided for data visualization
