Final answer:
Catheter ablation is the procedure that treats cardiac arrhythmias by using energy delivered through a thin intravascular tube to destroy heart tissue causing abnormal electrical signals.
Step-by-step explanation:
The treatment for cardiac arrhythmias that uses energy delivered by a thin intravascular tube is known as catheter ablation. This procedure is selected as a treatment for certain types of arrhythmias where medications or other interventions have not been effective. During catheter ablation, a thin flexible tube, or catheter, is inserted into a blood vessel, typically through the groin or neck, and guided to the heart tissue responsible for the arrhythmia. At this location, energy (radiofrequency, laser, or cryotherapy) is applied through the catheter to the problematic heart tissue to destroy small areas that are causing the abnormal electrical signals and restore a normal heart rhythm.
Catheter ablation is the treatment for cardiac arrhythmias that uses energy delivered by a thin intravascular tube. During the procedure, a catheter is inserted into the heart through a blood vessel, and energy is used to destroy or ablate abnormal electrical pathways causing the arrhythmia. This helps restore a normal heart rhythm.
