Abstract

Method and apparatus for cyclic ventricular pacing starting at a rate just above the intrinsic atrial firing rate (overdrive pacing), followed by relaxation to a rate just below the intrinsic atrial firing rate (ventricular escape). The method and apparatus can be applied to one or both ventricles, and can utilize one or more electrodes per ventricle. The electrode(s) can be applied to inner or outer ventricular surfaces. Relaxation protocols as a function of time can be linear, curvilinear to include exponential, or mixtures thereof. Furthermore, relaxation protocols can include one or more periods of time during which the pacing rate is held constant. Typically, the average ventricular pacing rate using this invention will be slightly greater than the intrinsic atrial firing rate, though alternate embodiments that encompass average ventricular pacing rates that are equal to or slightly less than the intrinsic atrial firing rate are also envisioned. Application of this method and apparatus to a heart in need thereof will produce a heart with an optimally minimized energy output requirement.

Description

[0001] divisional application

[0002] This application is a divisional application with application number 99806596.X, and the name of this application is "implantable pacemaker". technical field

[0003] The present invention generally relates to a pacemaker for controlling the heartbeat. More specifically, the present invention relates to a pacemaker for overdriving the ventricles by triggering at an average frequency slightly greater than the intrinsic (atrial) rate, cyclically promoting ventricular tracking of atrial pacing, and then gradually slowing down the ventricular stimulation To the point where ventricular beating is disconnected from atrial triggering, especially in combination with ventricular synchronization techniques such as biventricular pacing, biphasic, and / or multiple site ventricular pacing. Background technique

[0004] AV block, common in cardiac patients, occurs when electrical impulses traveling along the conduction tract from the sinoatrial node ...
