Dual chamber pacing system and method with optimized adjustment of the av escape interval for treating cardiomyopathy

Abstract From the Canadian patent

A dual chamber pacemaker system and method are provided for HOCM and like pacing therapy, with the feature of searching or scanning values of AV escape interval to define an optimized value at about the longest AV escape interval value consistent with full capture in response to a delivered ventricular pace pulse. In a preferred embodiment of the invention the system and method sense , and process FFRS signals derived from the atrial lead and otherwise and , obtain therefrom a characteristic which is evaluated for a determination of optimized AV escape interval. In one specific embodiment the time durations , between delivered ventricular pacing pulses and resulting FFRS signals are …
