Cardiac ablation is a procedure where catheters are placed in the heart and RF energy is delivered through the catheter. This neutralizes (ablates) the cardiac cells that are causing an arrhythmia by creating a block which the electrical impulses can no longer cross.
This restores the normal electrical pathways of your heart and allows it to beat normally again. The procedure is performed by a cardiac specialist called an Electrophysiologist (or EP). It is a widely used procedure, proven to be safe, effective, and long-lasting, although some arrhythmias are more easily treated with catheter ablation than others.
