ABSTRACT:
A method of operating a pacemaker and a pacemaker system that cuts short a pacemaker-defined refractory time period whenever capture is not achieved. The pacemaker generates a cardiac stimulation pulse, and in response thereto, initiates an evoked response detection time period and a refractory time period. If an evoked response occurs during the evoked response detection time period, capture is presumed. If an evoked response does not occur during the evoked response detection time period, then capture is not achieved and the refractory time period is terminated, or cut short, thereby lengthening the window during which natural cardiac activity may be sensed. In the event natural cardiac activity is not detected following the termination of the refractory time period, a backup stimulation pulse may be generated.
