“Magnetic Resonance Imaging in patients with ICDs and Pacemakers”
(if patient is an inpatient, it must be done before the patient returns to the floor).
An interrogation of the pacemaker or ICD will be performed 3 months after the exam to measure
thresholds (and other measurements).
Patient Care:
An ACLS certified Cardiology physician, nurse practioner or physician assistant, or alternatively,
an ACLS certified senior resident, fellow or attending physician of the primary care team will be
present at the MR-console during the entire exam to monitor the patient.
A pacemaker programmer will be present at the MR-scanner.
The patient will be monitored with ECG and pulse oximetry during the entire exam
A crashcart with an external defibrillator-pacemaker (not AED) must be present at the MR-
scanner.
A designated cardiologist needs to be within 5 minutes in of the MR-scanner.
