A tissue-level electromechanical model of the left ventricle: Application to the analysis of intraventricular pressure

Abstract

Abstract:The ventricular pressure profile is characteristic of the cardiac contraction progress and is useful to evaluate the cardiac performance. In this contribution, a tissue-level electromechanical model of the left ventricle is proposed, to assist the interpretation of left ventricular pressure waveforms.The left ventricle has been modeled as an ellipsoid composed of twelve mechano-hydraulic subsystems. The asynchronous contraction of these twelve myocardial segments has been represented in order to reproduce a realistic pressure profiles. To take into account the different energy
