Human Precardiac Zone Vibrations Analysis Using Parametric Spectral Methods

摘要

The article describes an approach of parametric spectral analysis application in apical seismocardiography using an example of the precardiac zone oscillations analysis. Parameters of individual sections of the cardio cycle can be investigated in detail using the proposed approach, which allows one to form a more accurate diagnostic representation of the heartbeat phases within the cardio cycle. The analysis of changes in the seismocardiographic signals modal composition depending on the position of a person during acquisition carried out. The presence of significant changes in the modal composition of such signals, which can be used as an additional diagnostic criterion, is shown.
