It depends on what type of pacemaker you have.  If it is a "rate-responsve" pacemaker then it will sense your activity and increase its rate.  If it is not then it should respond to an increase in your own sinus node rate response to exercise.  If however you have a condition called chronotropic incompentence then it may not respond to exercise.  Your doctor will have to tell you what type of pacemaker you have and what the best method to increase your heart rate it.  An alternative may be a test called a persantine test that does not require an increase in heart rate.
