Arrhythmias & electrophysiologyCohort study
Magnetic resonance imaging in patients with cardiac implantable electronic devices: the RESONANCE Spanish registry
- Prospective registry
- multicentre
- open-label
- 21 Spanish centres
Authors' conclusion
This registry revealed that only 3.5% of patients with CIEDs had an MRI referral over the study, with rates decreasing to 2.6% during the COVID-19 period.
