摘要：
In this work, the lumped parameter model of the left heart is presented. It is based on the concept of the time-varying elastance of myocardium and includes the model of the heart valve dynamics. Comparison of the models with instant and smooth valve opening and closing is given, as well as simulations of pathologies such as mitral valve stenosis and aortic valve insufficiency are addressed.
