Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older who have atrial fibrillation and are eligible for MRI scans.
✕Probably not a fit
Patients who may not benefit include those who are pregnant, hemodynamically unstable, or have contraindications for cardiac MRI.

What this trial studies
This study evaluates a novel MRI-conditional 12-lead ECG monitoring system developed by MiRTLE Medical, designed to improve the detection of arrhythmias and ischemia during cardiac MRI scans. Currently, standard care uses a 3-lead ECG system, which may not adequately monitor patients with atrial fibrillation undergoing MRI. The new system aims to reduce interference from MRI's magnetic fields and radio frequency pulses, potentially enhancing patient safety and diagnostic accuracy. The study will assess the efficacy of this advanced ECG system in a clinical setting.
Why it matters
Potential benefit: If successful, this new ECG system could significantly improve the safety and diagnostic capabilities during MRI scans for patients with atrial fibrillation.
How similar studies have gone: While this approach is innovative, similar studies have not been widely reported, making this a potentially novel evaluation.
