Electrophysiology Study (EPS) and Radiofrequency Ablation

Electrophysiology (EP) study with radiofrequency ablation is a specialised procedure used to identify and treat abnormal heart rhythms. The EP study helps map the electrical activity of the heart, while ablation treats the faulty area responsible for the arrhythmia by applying controlled heat energy to destroy it.

This is done to treat patients with recurrent palpitations, supraventricular tachycardia (SVT), atrial flutter, or certain types of ventricular tachycardia. When medications are ineffective or not preferred, ablation offers a permanent solution with high success rates.

The procedure is done in a catheterisation lab. Thin wires (catheters) are inserted through veins in the groin or neck and guided to the heart. Electrical signals are studied to pinpoint the abnormal circuit. Once located, radiofrequency energy is delivered to ablate the area. The procedure may take two to four hours and is usually done under sedation or general anaesthesia.

EP study and ablation are recommended for patients with drug-resistant arrhythmias, frequent episodes affecting daily life, or those wanting to avoid long-term medications. It is a definitive treatment option in many rhythm disorders.
