Classification: A61N

Abstract:
1. A method of providing cardiac potentiation therapy, the method comprising: sensing an atrial depolarization; delivering a premature atrial pace based on the sensed atrial depolarization at a first time interval following the sensed atrial depolarization; sensing a ventricular depolarization; delivering a premature ventricular pace based on the sensed ventricular depolarization at a second time interval following the sensed ventricular depolarization; and selecting the first time interval to be greater than a non-nodal atrial refractory period caused by the sensed atrial depolarization and less than a sino-atrial node refractory period caused by the sensed atrial depolarization to prevent the sino-atrial node from being depolarized by the premature atrial pace.
