Catheter ablation (also known as radiofrequency catheter ablation) is a non-surgical technique where a thin electrode catheter (a specially insulated electrical wire) is used to localise the abnormal site in the heart causing the
arrhythmia (electrical disorder of the heart). Radiofrequency energy is then delivered via the catheter to ablate (or destroy) it. It is an extension of the
electrophysiological study (EPS).
