Stanford Cardiac Arrhythmia Service

Chemical Ablation

Chemical ablation is another non-surgical technique the Stanford Arrhythmia Service has at its disposal. Just as catheter ablation and cryoablation use heat and cold respectively to treat an arrhythmia, chemical ablation uses a chemical mixture injected at the source of the arrhythmia to interrupt the electrical impulses that cause it.

Your physician will determine the exact location of the arrhythmia source during an electrophysiology study (EPS) and, when possible, he or she will perform the chemical ablation right after the study. The chemical ablation works by creating a lesion or scar in the location of the electrical cells that are causing the arrhythmia.
