Radiofrequency ablation (RFA)
RFA is a minimally-invasive procedure used to stop dangerous arrhythmias (abnormal or irregular heartbeats) in this procedure, doctors guide long, flexible tubes (catheters) through your blood vessels to your heart. The catheter has an electrode at the tip that will help your doctor locate the area(s) causing the arrhythmia. Then the catheter tip can transmit energy to burn or destroy that area and terminate the arrhythmia. This procedure usually takes about 3 or 4 hours to complete but may take longer.
