Abstract:Objective To explore the clinical application of patients with cardiac magnetic resonance compatible pacemakers
implanted in cardiovascular magnetic resonance (CMR) examination. Methods From January 2020 to December 2021, a total of
10 patients with implanted magnetic resonance compatible pacemakers in our hospital were enrolled. Before the CMR examination,
the instructions for the examination process should be educated using diagrams. During the examination, doctors, technicians,
nurses and engineers cooperated to ensure that the examination was carried out thoroughly, completed the necessary nursing
operations and psychological communication with the patients during the scanning interval, conducted individualized visits after
the examination, recorded the observation indicators for statistical analysis. Results All 10 patients implanted magnetic resonance
compatible pacemakers completed CMR examination, which took an average of (45±6) min, and the SAR value did not exceed the
limit standard. There was no abnormal change in heart rate and blood pressure, and no irregular pulse of pacemaker before and after
examination. The satisfaction score of overall examination process was (4.4±0.6), and the satisfaction with professional knowledge
was the highest. Conclusion For patients with implanted magnetic resonance compatible pacemakers to undergo CMR examination,
detailed clinical observation indicators should be formulated. The corresponding procedures should be coordinated to play a positive
role in ensuring patient safety and improving satisfaction.
