Magnetic Resonance Imaging (MRI) uses powerful magnetic waves to produce images of the soft tissue on the interior of the human body. Many patients with implanted heart devices are not eligible to have an MRI scan. Because the FDA has not approved their pacing systems for use during an MRI scan or near MRI scanners.
A new model of an implantable cardioverter defibrillator (ICD) . Which is resistant to the MRI’s strong magnetic fields, has passed EMF Testing. At Golden Jubilee Hospital in Clydebank, West Dunbartonshire. The Ellipse ICD, developed by US manufacturer St Jude Medical, will now be tested in a further 165 patients at 60 MRI centers around the world. The Guernsey Press reported on August 24, 2016. These devices should “shock the heart back into rhythm when it detects a potential cardiac arrest.”
What is MRI Protection Mode? In preparation for an MRI scan. A clinician programs the pulse generator in an MR-Conditional system to MRI Protection Mode using the PRM. MRI Protection Mode modifies the behavior of the device, and its design accommodates the electromagnetic environment of the scanner. Additionally, a clinician may program a time-out feature to cancel MRI Protection mode after a specified number of hours.
