Which treatment for cardiac arrhythmias uses energy delivered by a thin intravascular tube?

The treatment for cardiac arrhythmias that uses energy delivered by a thin intravascular tube is called catheter ablation. During this procedure, a catheter is inserted into a blood vessel and guided to the heart, where it delivers radiofrequency energy, cryotherapy, or other forms of energy to destroy the abnormal electrical pathways causing the arrhythmia. This minimally invasive technique can effectively restore normal heart rhythm and alleviate symptoms.
