Rhythmical fluctuations of the arterial blood pressure in animal with total artificial heart

In order to investigate the origin of the fluctuations in hemodynamic parameters, total artificial heart (TAH) replacement was performed in chronic animal experiments using adult goats. Two ventricular assist devices were implanted as total biventricular bypass (BVB) and natural heart was electrical...

Description
Summary:In order to investigate the origin of the fluctuations in hemodynamic parameters, total artificial heart (TAH) replacement was performed in chronic animal experiments using adult goats. Two ventricular assist devices were implanted as total biventricular bypass (BVB) and natural heart was electrically fibrillated. The results suggest that fluctuations in the hemodynamics of the TAH animal are originated from the periodicity of the peripheral and pulmonary vascular resistance.
