The assessment bioenergy of cardiac contraction in the conditions of mechanical support circulation

Aim: to develop a new modified index for the assessment of bioenergy heart in conditions of heart failure. To assess the energy of the heart when using systems to bypass the left ventricle of the heart using non-pulsed flow pumps. To consider the fundamental advantage of non-pulsating flow pumps with the generation of a pulsating flow in the cardio-synchronized copulsation mode over the counterpulsation mode.
