MRI CAN PREDICT RISK OF CARDIAC ARRHYTHMIA BY IDENTIFICATION OF SCAR TISSUE

Magnetic resonance imaging can now be used to predict the risk for a fast and dangerous heart rhythm known as ventricular arrhythmia. Patients whose muscle wall thickness contained over 25 percent of scar tissue are nine times more likely to likely to test positive according to researchers at Johns Hopkins Institute. If the findings can be extrapolated to accurately predict the risk of arrhythmia-related sudden death, MRI could soon turn out to be a gold standard in the screening of high-risk cardiac patients. It can even determine the need for the placement of a defibrillator in such individuals.
