In this paper a method for estimating maximum ventricular elastance through a switched observer is proposed, based on measurement of ventricular volume (and possibly aortic pressure). The proposed switched observer, i.e, an observer for a switched system, is derived from an electrical-analog model of the left ventricle and systemic load. An observability study was a priori conducted on the model, restricted to the ejection phase, to validate the estimation procedure. The method has been evaluated with simulated data and produced good results.

Abstract

In this paper a method for estimating maximum ventricular elastance through a switched observer is proposed, based on measurement of ventricular volume (and possibly aortic pressure). The proposed switched observer, i.e, an observer for a switched system, is derived from an electrical-analog model of the left ventricle and systemic load. An observability study was a priori conducted on the model, restricted to the ejection phase, to validate the estimation procedure. The method has been evaluated with simulated data and produced good results.
