    摘要: An implantable medical device for monitoring the movements of the valve planes of the heart to determine at least one hemodynamic measure reflecting a mechanical functioning of a heart of a patient, includes an impedance measuring circuit that measures impedance between at least electrode pairs including at least one electrode placed substantially at the level of the valve plane. The measured impedances reflect valve plane movements. A hemodynamic parameter determining circuit determines at least one hemodynamic parameter based on the impedances reflecting the mechanical functioning of the heart.
