Outcome Measures

Primary Outcomes (2)

  • Device Malfunction

    Number of patients with change in device testing defined as a change in any of the following (impedance, battery life, p and r wave sensing and atrial and ventricular capture thresholds) not to exceed 50 percent from baseline

    immediately post MRI (up to 2 hours) and long-term follow-up (up to 6 months)

  • Patient Safety

    Number of patients with change in vital signs including blood pressure, heart rate and pulse oximetry not to exceed 10 percent from baseline lead impedances as well as patient reports of any discomfort related to MRI)

    assessed during MRI and immediate post MRI (up to 2 hours)

Secondary Outcomes (1)

  • Noise Artifacts as Assessed by the Number of Participants With a Greater Than a 50% Change in Lead Impedance

    Immediately post MRI (up to 2 hours)

Study Arms (1)

MRI and Cardiac Devices

Clinically indicated MRI (all types) in patients with implanted pacemakers and ICD
