New Method for Detection of Ventricular Suction in an Implantable Pump Using Recursive DFT Algorithm

Abstract

In this paper, a brand new technique for detection of ventricular suction in a Rotary Left Ventricular Assist Device (LVAD) helping a failing cardiovascular gadget the usage of recursive DFT algorithm is presented. The algorithm is developed by the author and used in different frequency data measurement. The suction detection is primarily based on-line frequency data measurement of a periodic signals. The algorithm is computationally easy with a small variety of mathematical parameters and comparatively easy to implement. Simulation were carried out on a fifth-order lumped parametric circuit which can produce the cardiovascular system combined with a rotary pump to illustrate responsiveness and robustness of the algorithm.
