Abstract
A cardiac stimulator and a method of its use. The stimulator includes a lead system carrying a stimulation electrodes adapted to be located at multiple sites adjacent tissue of a patient's heart and is provided with stimulation pulse generators coupled to deliver stimulation pulses to the stimulation electrodes. The stimulator further includes depolarization sensors responsive to depolarizations of cardiac tissues at the tissue sites and, responsive to sensed depolarizations and stimulation pulses delivered to said sites by said stimulation electrodes determines exitable gaps of tissue at the sites. The stimulator calculates stimulus pulse delivery times at variable delivery times within the determined exitable gaps at the tissue sites to cause convergence of depolarization cycles at the tissue sites over a series of delivered stimulation pulses and delivers stimulation pulses to the stimulation electrodes at the calculated variable delivery times.
