A closed-loop mathematical model successfully captures the predominant features of BCG signals, providing a quantitative framework for clinical interpretation and device optimization.
Objective: to develop quantitative methods for the clinical interpretation of ballistocardiogram (BCG). Methods: a closed-loop mathematical model of the system is proposed to theoretically simulate the mechanisms the BCG signal, which is then compared with the signal acquired via on a suspended bed. Results: simulated arterial pressure and ventricular functions are in good qualitative and quantitative with those reported in the clinical literature. Simulated BCG signals the typical I, J, K, L, M and N peaks and show good qualitative and agreement with experimental measurements. Simulated BCG signals with reduced contractility and increased stiffness of the left exhibit different changes that are characteristic of the specific condition. Conclusion: the proposed closed-loop model captures the features of BCG signals and can predict pathological changes on the of fundamental mechanisms in cardiovascular physiology. Significance: work provides a quantitative framework for the clinical interpretation of signals and the optimization of BCG sensing devices. The present study an average human body and can potentially be extended to include among individuals.
