Seismocardiography (SCG) monitors health metrics through body surface vibrations from heart activity. The BEAT experiment required echocardiography (ECHO) to correlate SCG signals with cardiac events. Since no standardized ECHO protocol existed, the authors developed one. The protocol focused on recording mitral and aortic valve openings and closings using multiple ECHO modalities for accuracy, ensuring usability, comfort, and efficient data collection. It was tested on healthy subjects and allowed post-hoc analysis of cardiac function. This standardized protocol aims to enhance comparability across SCG studies and offers a reliable method for correlating SCG signals with cardiac events.
