After screening for aortic and mitral valve timing events, 12 studies were selected. These studies focused on correlating SCG signals with ECHO using M-mode, PW-Doppler, CW-Doppler, and TDI. Variations in sensor placement and subject positioning highlighted the need for standardization. Our review stresses the importance of clear objectives, standardized protocols, and recording disease-specific impacts on heart mechanics for future research.en1879-83652025364368IOS Presshttps://creativecommons.org/licenses/by-nc/4.0/Cardiac timing events | Echocardiography | Seismocardiography | StandardizationTechnology::616: DeseasesTechnology::610: Medicine, HealthTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringReview Articlehttps://doi.org/10.15480/882.1514110.3233/SHTI25011310.15480/882.15141Review Article
