Cardiac Ablation (EPS and Catheter Ablation)

Cardiac ablation is a catheter-based treatment for heart rhythm disorders, usually performed together with an electrophysiology study, or EPS, that maps the electrical circuits of the heart from the inside. Thin, flexible catheters are guided through a vein, most often in the groin, up into the heart, where they record electrical signals and pinpoint the tissue that is triggering or sustaining the abnormal rhythm. That small area is then neutralised, either with radiofrequency energy that heats the tissue or with cryoablation that freezes it, so the faulty circuit can no longer fire. The procedure is done under sedation or general anaesthesia, usually takes two to four hours, and most people stay in hospital for one to two days. For many rhythm problems, including supraventricular tachycardia and atrial fibrillation, ablation can reduce or stop episodes and cut the need for long-term rhythm medication, which is why patients often seek experienced electrophysiology teams abroad.
