Developing a Protocol for Aligning and Correlating Seismocardiography with Echocardiography.

Area of Science:

• Biomedical Engineering
• Cardiology
• Medical Instrumentation

Background:

• Seismocardiography (SCG) measures cardiac activity via body vibrations.
• Echocardiography (ECHO) is crucial for validating SCG signals.
• A lack of standardized ECHO protocols hinders SCG research.

Purpose of the Study:

• To develop and validate a standardized echocardiography (ECHO) protocol.
• To correlate seismocardiography (SCG) signals with specific cardiac events.
• To improve the reliability and comparability of SCG-based health monitoring.

Main Methods:

• Developed a protocol for recording mitral and aortic valve dynamics using multiple ECHO modalities.
• Focused on accuracy, usability, subject comfort, and efficient data acquisition.
• Tested the protocol on healthy participants for post-hoc cardiac function analysis.

Main Results:

• Successfully established a standardized ECHO protocol for SCG validation.
• Demonstrated the protocol's effectiveness in capturing key cardiac valve events.
• Enabled detailed post-hoc analysis of cardiac function in conjunction with SCG data.

Conclusions:

• The developed standardized ECHO protocol enhances the accuracy of SCG signal interpretation.
• This standardization is vital for improving the comparability and reliability of future SCG studies.
• Offers a robust method for correlating SCG with cardiac events, advancing non-invasive cardiac monitoring.
