Echocardiography Correlation with Seismocardiography-Systematic Review.

Area of Science:

• Biomedical Engineering
• Cardiovascular Physiology
• Medical Instrumentation

Background:

• Seismocardiography (SCG) offers a non-invasive method for assessing cardiac function.
• Echocardiography (ECHO) is the gold standard for evaluating heart mechanics and valve function.
• Correlating SCG with ECHO can enhance diagnostic capabilities.

Purpose of the Study:

• To systematically review studies correlating seismocardiography (SCG) and echocardiography (ECHO) signals.
• To identify methodologies used for comparing SCG and ECHO, specifically for aortic and mitral valve timing.
• To highlight areas for standardization in SCG research.

Main Methods:

• A systematic literature review was conducted using Scopus, PubMed, and IEEE-Explore.
• 61 studies on SCG and ECHO were initially identified.
• 12 studies focusing on aortic and mitral valve timing events were selected for detailed analysis.

Main Results:

• Selected studies correlated SCG signals with ECHO using M-mode, PW-Doppler, CW-Doppler, and TDI.
• Significant variations in sensor placement and subject positioning were observed across studies.
• The review identified a need for standardized protocols in SCG data acquisition.

Conclusions:

• Standardization of sensor placement and subject positioning is essential for reliable SCG measurements.
• Future research should focus on clear objectives and standardized protocols.
• Incorporating disease-specific impacts on heart mechanics is vital for advancing SCG applications.
