A prospective evaluation of a protocol for magnetic resonance imaging of patients with implanted cardiac devices.

ABSTRACT:

Background

Magnetic resonance imaging (MRI) is avoided in most patients with implanted cardiac devices because of safety concerns.

Objective

To define the safety of a protocol for MRI at the commonly used magnetic strength of 1.5 T in patients with implanted cardiac devices.

Design

Prospective nonrandomized trial. (ClinicalTrials.gov registration number: NCT01130896) SETTING: One center in the United States (94% of examinations) and one in Israel.

Patients

438 patients with devices (54% with pacemakers and 46% with defibrillators) who underwent 555 MRI studies.

Intervention

Pacing mode was changed to asynchronous for pacemaker-dependent patients and to demand for others. Tachyarrhythmia functions were disabled. Blood pressure, electrocardiography, oximet
