Patent ID: 7970471

Claim:
A cardiac rhythm management device, comprising: a sense amplifier for connecting to an electrode to form an evoked response sensing channel for detecting an evoked response generated after delivery of a pacing pulse; a plurality of pulse generators for connecting to electrodes to form a plurality of pacing channels for delivering paces to a selected heart chamber; a controller for controlling the delivery of pacing pulses by a selected pacing configuration in accordance with a programmed pacing mode associated with the pacing configuration, wherein the pacing configuration specifies which pacing channels are to be used for delivery of pacing pulses; and, wherein the controller is programmed to: perform a capture verification test at a selected time to test a selected pacing channel for presence or loss of capture during a pacing pulse, the capture verification test being performed by detecting whether an evoked response occurs during a capture detection window following the output of a pacing pulse; and, switch from the selected pacing configuration and associated pacing mode to a next pacing configuration and associated pacing mode contained in an ordered list upon detection of a loss of capture in a pacing channel making up the selected pacing configuration, wherein the next pacing configuration does not include the pacing channel in which the loss of capture was detected.
