A method for reducing the affects of intrinsic detection latency in a cardiac rhythm management device, wherein said method is initiated immediately prior to delivering a stimulation pulse to the heart tissue. A coincidence of intrinsic and cardiac rhythm management initiated stimulus or the delivery of a stimulation pulse proximate the time of an intrinsic event due to intrinsic detection latency may results in delivery of unnecessary backup stimulus and/or imprecise determination of a pacing threshold. When stimulating the heart, the timing sequence for delivering a stimulation pulse typically depends upon the timing of a previous intrinsic or device initiated event. Further, the method of the present invention reduces the affects of intrinsic detection latency thereby facilitating improved detection of capture and determination of capture threshold for minimizing power consumption while assuring therapeutic efficacy.
A cardiac rhythm management device for reducing the affects of intrinsic detection latency, said device comprising means for sensing cardiac electrogram signals, a programmable controller coupled to receive the sensed electrogram signals, and stimulation means controlled by the controller for applying cardiac stimulation pulses to a patient's heart in response to control signals from the controller on a beat-to-beat basis, wherein said controller reduces the affects of intrinsic detection latency by:
