Radiofrequency ablation is a non-invasive procedure used to treat some
types of arrhythmias.
The procedure is done by a physician guiding a catheter with an electrode
at its tip to the area of the heart muscle where there is a pathway. The

area from conducting the additional impulses that are causing the rapid
