Patent number: 11938326Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.Type: GrantFiled: February 18, 2022Date of Patent: March 26, 2024Assignee: Medtronic, Inc.Inventors: Hyun J. Yoon, Wade M. Demmer, Matthew J. Hoffman, Robert A. Betzold, Jonathan D. Edmonson, Michael L. Ellingson, Mark K. Erickson, Ben W. Herberg, Juliana E. Pronovici, James D. Reinke, Todd J.
