Development of a Presentation Interface for Seismo- and Ballistocardiographic Data

Area of Science:

• Biomedical Engineering
• Cardiovascular Physiology
• Signal Processing

Background:

• Ballistocardiography (BCG) non-invasively measures forces from cardiac activity.
• Establishing reference signals is crucial for clinical applications.

Purpose of the Study:

• To create a comprehensive reference database for ballistocardiography signals.
• To develop intuitive data representation methods for BCG.

Main Methods:

• Collected BCG data from 34 healthy adults using varied setups and sensor positions.
• Acquired data during resting and physical stress (ergometer, treadmill) conditions.
• Processed over 18 hours of signal data across 72 datasets.

Main Results:

• Developed the first reference database for ballistocardiography signals.
• Created a prototype for naive data representation.
• Implemented a user interface for live and retrospective BCG data visualization.

Conclusions:

• The established BCG database serves as a valuable resource for research.
• The developed interface facilitates intuitive understanding of BCG data.
• This work paves the way for enhanced diagnostic capabilities using BCG.
