In this work, the effect of high heart rate on the LDL transport in arteries is examined using the finite element method. The velocity profile is pulsatile, while the tachycardia case is assumed to have 40% increased flow rate and 25% increased velocity than the normal case. The Navier-Stokes equations are used to model the blood flow and LDL transfer is modeled using the convection-diffusion equation...
The ultimate hemodynamic sensor for an implantable device would provide information about cardiovascular performance including systolic function, diastolic function, preload, and afterload. We examined the potential clinical utility of simultaneous measurement of left ventricular pressure and continuous intrathoracic impedance in a group of 20 patients undergoing acute intravenous ablation for atrial...
