Catheter ablation is a procedure that treats heart rhythm
problems by destroying tiny areas of heart tissue that are causing the
problems. Guided by X-rays, the doctor inserts thin tubes called catheters into
a blood vessel, typically
in the groin or neck, and feeds them into the
Wires in the catheters help the doctor identify the type
of rhythm problem and find the problem areas. Then the doctor uses the wires to
send energy—heat or freezing cold—to those areas. The energy destroys, or
ablates, the tissue. After it's destroyed, the tissue can no longer cause a
problem. The areas of tissue are very tiny. And destroying them does not affect
the heart's ability to do its job.
