1/f Fluctuation in Total Artificial Heart

  • Conference paper
Heart Replacement

Summary

The spectral profile of fluctuations of hemodynamic parameters was investigated in the natural heart, the total artificial heart (TAH) with fixed drive condition, and in the TAH with automatic (1/R) control. The inverse frequency (1/f) fluctuations were found in the heart rate (HR) and peripheral conductance (1/TPR) in the natural heart, and in the pulse rate (PR) and 1/TPR in the TAH with 1/R control. The PR of the TAH with 1/R control is considered to have some compatibility with the HR of the natural heart, although the control loop is completely different.
