- Number of Patients with adverse events as a measure of Safety and Tolerability [ Time Frame: 1-2 hours and up to 5 years ] [ Designated as safety issue: Yes ]Changes in device testing pre vs. post MRI and long-term follow-up (at 3 months and longest follow-up att he time of analysis; up to 5 years post MRI)Tests include pacing thresholds, sensing, battery life and lead impedences as well as patient reports of any discomfort related to MRI
- Imaging artifacts produced by the implanted device and device sensing of noise artifact produced by MRI [ Time Frame: 1 -2 days ] [ Designated as safety issue: No ]We will evaluate whether or not the artifacts produced are significant enough to prevent dignostic interpretation of images

Detailed Description:
This prospective cohort study to use an established MRI device safety protocol to decrease the risk of clinically indicated MR imaging in patients with implantable cardiac devices. All devices will undergo a complete interrogation and testing of thresholds, sensing, battery voltage and impedances prior to and following imaging. Pre-MRI, devices will be programmed to setting that will ensure MRI safety. During imaging, patients will blood pressure, heart rate and O2 sat level will be monitored continuously.
