Table 4 Recommendations for CMR in patients with ventricular arrhythmias and for the prevention of sudden cardiac death

From: Role of cardiovascular magnetic resonance in the guidelines of the European Society of Cardiology

Non-invasive evaluation of patients with suspected or known ventricular arrhythmias Classa Levelb Page
 Pharmacological stress testing plus imaging modality is recommended to detect silent ischaemia in patients with ventricular arrhythmias who have an intermediate probability of having coronary artery disease by age or symptoms and are physically unable to perform a symptom-limited exercise test. I B 12
 CMR or CT should be considered in patients with ventricular arrhythmias when echocardiography does not provide accurate assessment of LV and RV function and/or evaluation of structural changes. IIa B 12
Management of ventricular arrhythmias in inflammatory heart disease Classa Levelb Page
 Demonstration of persistent myocardial inflammatory infiltrates by immunohistological evidence and/or abnormal localized fibrosis by CMR after acute myocarditis may be considered as an additional indicator of increased risk of SCD in inflammatory heart disease. IIb C 53
Prevention of sudden cardiac death in athletes Classa Levelb Page
 Upon identification of ECG abnormalities suggestive of structural heart disease, echocardiography and/or CMR imaging is recommended. I C 62
