Radio Frequency Ablation (RFA)

What Is It?

Is an invasive procedure done to treat abnormal heart rhythms.

How Is It Done?

At the time of an electrophysiological study (EPS) if a suitable heart rhythm is identified a special catheter (electrical wire) is maneuvered into place at a site critical to the abnormal rhythm. Electrical current is the passed down the catheter that heats the tip and tissue at this site destroying this area and usually curing the abnormal rhythm. It is also performed by cooling the catheter, which is called cryoablation.

Why Is It Done?

RFA is performed to try and permanently cure the abnormal rhythm.
