Catheter is a procedure used to selectively destroy areas of the heart that are causing a heart rhythm problem. During this procedure, thin, flexible wires are inserted into a blood vessel in the thigh, groin, neck, or elbow and threaded up through the blood vessel and into the heart under X-ray guidance. The wires allow the doctor to record the electrical activity of your heart and determine what kind of heart rhythm problem you have.
Catheter that uses radio waves is called radiofrequency catheter ablation. These radio waves can be delivered to your heart muscle at the site of the “short circuit.” The radio waves (radiofrequency energy) cause a tiny area of heart muscle to be heated and selectively destroyed (ablated), thereby curing your heart rhythm problem. New energy sources for catheter ablation such as liquid nitrogen (cryoablation) are being used. But there is no evidence that these new energy sources are better than the standard radiofrequency catheter ablation. Using foley catheter can eliminate patient exposure to the latex
