Abstract

In order to analyze the autonomic nervous system during left ventricular assistance using oscillated blood flow with Vibrating Flow Pump (VFP), fluctuations of the hemodynamic parameters were evaluated by the fast fourier transform with beat-to-beat basis. Chronic animal experiments of the left heart bypass with VFP using four healthy adult goats were performed. Specral analysis of the hemodynamic parameters were performed for the evaluation of the autonomic nervous system. Our results suggest that Mayer wave fluctuations of the hemodynamics were significantly decreased during left heart bypass with VFP, suggesting that sympathetic tone were decreased during left heart bypass with oscillated blood flow.
