ABSTRACT:
A method and apparatus for actively determining a coupling interval corresponding to a cardiac vulnerable zone associated with a therapy of an implantable medical device that includes a timing and control unit delivering, via electrodes of a plurality of electrodes, a first pulse train and a first pulse signal at a predetermined time interval from delivery of a last pulse of the first pulse train. A sensor determines an evoked response corresponding to the first pulse signal, and a microprocessor compares the evoked response to a prior determined evoked response and sets the coupling interval equal to the predetermined time interval in response to the evoked response having increased by a first predetermined amount, and reduces the predetermined time interval by a second predetermined amount in response to the evoked response not having increased by the first predetermined amount.
