<p>A method and device for delivering therapy that includes an electrode to sense cardiac signals and to deliver a therapy, a monitoring module detecting a cardiac event in response to the sensed cardiac signals using first detection criteria, a sensor emitting light and detecting emitted light scattered by a tissue volume adjacent the sensor to generate a corresponding detected light intensity output signal, a control module coupled to the sensor to control light emission of the sensor in response to delivering the therapy, and a controller coupled to the monitoring module, the therapy delivery module and the sensor, the controller configured to determine tissue oxygenation measurements in response to the output signal, determine a tissue oxygenation trend in response to the tissue oxygenation measurements, determine a recovery index in response to the determined tissue oxygenation trend, and control one or both of detecting a cardiac event by the monitoring module and delivery of therapy by the therapy delivery module in response to the determined recovery index.</p> |
