Abstract
A pacemaker initiates and times a monitoring interval in response to an event such as a therapy delivery to a patient. The monitoring interval is specified to include a duration of an anticipated acute response to the event, such as vagal surge. One or more physiological parameters indicative of the acute response are detected during the monitoring interval for analyzing therapeutic effect of the event. In various embodiments, one or more pacing parameters are adjusted for a response interval specified to include the duration of the anticipated acute response to allow for the analysis and maximization of the therapeutic effect. In various embodiments, the event includes a session of pacing therapy delivered according to an intermittent cardiac stress augmentation pacing protocol, and the therapeutic effect is analyzed to adjust that protocol.
