Abstract
Official abstract text for this publication.
Systems and methods for arrhythmia therapy in MRI environments are disclosed. Various systems disclosed utilize ATP therapy rather than ventricular shocks when patients are subjected to electromagnetic fields in an MRI scanner bore and shock therapy is not available. As the patient is moved out from within the scanner bore and away from the MRI scanner, the magnetic fields diminish in strength eventually allowing a high voltage capacitor within the IMD to charge if necessary. The system may detect when the electromagnetic fields no longer interfere with the shock therapy and will transition the IMD back to a normal operational mode where shock therapy can be delivered. Then, if the arrhythmia still exists, the system will carry out all of the system's prescribed operations, including the delivery of electric shocks to treat the arrhythmia.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for operating an implantable medical device (IMD) implanted within a patient in the presence of a magnetic resonance imaging (MRI) environment, the method comprising: receiving a therapy command from an external device while the IMD is in the presence of an MRI electromagnetic field and is operating in a first operational mode in which one or more sensors of the IMD have been disabled, the therapy command configured to prompt the IMD to provide imme…
