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