20090254141 | APPARATUS AND METHOD FOR REVERSAL OF MYOCARDIAL REMODELING WITH ELECTRICAL STIMULATION - An apparatus and method for reversing ventricular remodeling with electro-stimulatory therapy. A ventricle is paced by delivering one or more stimulatory pulses in a manner such that a stressed region of the myocardium is pre-excited relative to other regions in order to subject the stressed region to a lessened preload and afterload during systole. The unloading of the stressed myocardium over time effects reversal of undesirable ventricular remodeling. | 10-08-2009 |
