Rewires the heart: Electrical impulses cause the muscle fibers of the heart to contract and are carried through the heart by special fibers that act like the electrical wires in your home. With svt, often there is an extra fiber present that allows the electrical impulses to bypass the heart's normal circuitry, leading to abnormal rhythms. Using a special catheter, this "extra" fiber can be ablated (destroyed).

Very effectively.: The supraventricular tachycardia is a short-circuit of the normal heart conduction pathways. Usually there is a small area that, if removed, would Prohibit the circuit from conducting and therefore block the svt. The catheter tip generates rf energy to scar the heart tissue in a small area, which prevents it from conducting electricity.
