1. A method comprising:
- controlling a cardiac pacing rate of an implantable medical device (IMD) to control a heart rate of a patient;
determining that the patient is in a resting state; and
modifying the pacing rate of the IMD for N cardiac cycles in response to determining that the patient is in the resting state, wherein N is an integer greater than 1, and wherein modifying the pacing rate comprises;
incrementally increasing the pacing rate for a first portion of the N cardiac cycles; and
incrementally decreasing the pacing rate for a second portion of the N cardiac cycles; and
discontinuing modification of the pacing rate when at least one of a predetermined amount of time has passed since determining that the patient is in the resting state and a predetermined number of cardiac cycles have passed since determining that the patient is in the resting state.

Abstract
A method includes controlling a cardiac pacing rate of an implantable medical device (IMD) to control a heart rate of a patient and determining that the patient is in a resting state. The method further includes modifying the pacing rate of the IMD for N cardiac cycles in response to determining that the patient is in the resting state. N is an integer greater than 1. Modifying the pacing rate includes incrementally increasing the pacing rate for a first portion of the N cardiac cycles, and incrementally decreasing the pacing rate for a second portion of the N cardiac cycles.
