Catheter ablation for cardiac arrhythmias
Dr Jonathan C Pitts Crick
Most tachycardia (fast heart beat) problems can now be treated by RF catheter ablation which was pioneered in Bristol. The ablation procedure involves insertion of catheters through a vein under local anaesthetic and measurements to identify the cause of the problem (Electrophysiology study). One catheter is then precisely positioned at the site of the abnormal connection and high frequency electrical energy (which does not cause a shock) is delivered to the site causing ablation, or block, to the pathway.
