Feedback effects in heart-arterial system interaction.
Dynamic arterio-ventricular interaction in terms of left ventricle elastance and nonlinear arterial system compliance, pulse wave reflections and coronary blood flow was investigated, combining the use of analog models of the circulation with data from animal experiments. Results show that dynamic factors, as well as "feedback" effects are important.
