Radio- Freauency Ablation Therapy for Cardiac Arrhythmias

Radio-frequency catheter ablation has replaced anti-arrhythmic-drug therapy for the treatment of many types of cardiac arrhythmia (Miller and Zipes, 2005).Catheter-ablation procedures are performed in an electro-physiology laboratory. Usually both the diagnosis and the catheter ablation can be accomplished in a single session. Three or four electrode catheters are inserted percutaneously into a femoral, internal jugular or subclavian vein and positioned within the heart to allow pacing and recording at key sites (Erdogan, 2005).
