Claim:
1. An implantable medical device comprising: a therapy module configured to generate pacing therapy for a heart of a patient; and a control module configured to detect a condition indicative of the presence of a magnetic resonance imaging (MRI) device, switch operation from a first pacing therapy program to a second pacing therapy program in response to detecting the condition indicative of the presence of the MRI device, and while operating in the second pacing therapy program, control the therapy module to generate a pacing pulse to an atrium of the heart of the patient during a time period between the end of an atrial refractory period of a previous atrial depolarization and the end of a ventricular refractory period of a previous ventricular depolarization corresponding to the previous atrial depolarization.
