Summary
Ventricular fibrillation during cardiac MRI was documented with simultaneous recordings. This unique data provided insights into the arrhythmia mechanism, improving understanding of sudden cardiac events.
Area of Science:
- Cardiology
- Medical Imaging
- Electrophysiology
Background:
- Life-threatening arrhythmias in hospitals are often poorly documented, impeding mechanistic understanding.
- Accurate documentation is crucial for advancing knowledge of cardiac arrhythmias.
Observation:
- A patient with coronary artery disease experienced ventricular fibrillation during a cardiovascular magnetic resonance (CMR) scan.
- The ventricular fibrillation occurred immediately post-contrast agent injection during a resting quantitative myocardial perfusion sequence.
Findings:
- This is the first documented case of ventricular fibrillation during CMR with simultaneous electrocardiographic, physiological, and quantitative myocardial perfusion data.
- Comprehensive analysis of the preceding events offered a well-reasoned conclusion on the arrhythmia's mechanism.
Implications:
- This case provides unique insights into the potential triggers and mechanisms of ventricular fibrillation during cardiac MRI.
- Such detailed documentation can improve the understanding and management of arrhythmias in cardiovascular imaging settings.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
