Local anaesthesia is given in the upper part of thigh and a plastic sheath is placed inside the artery or vein. Different catheters are taken up to the heart through these sheaths. The external end of the catheter is connected to the computerised console through a wire. This computer constantly displays the cardiogram obtained through the tip of the catheter from within the heart. This graph gives total information about the conduction system of the heart and impulse travelling through it. On the basis of systematic study of this graph, the electrophysiologist (cardiologist) can decide the location of defect in the conduction system. This is quite similar to what an electrician does when we call him for correcting the electric fault at our place !
During this entire procedure, patient’s heartbeats, ECG, blood pressure and level of oxygen in the blood are continuously monitored.
During EPS, once that abnormal extra wire / focus is found, heart (radio frequency energy) is delivered through a catheter and that focus is burnt (ablated). This is called RFA.
A patient does not experience any specific problem or pain in the heart during this procedure. This procedure is almost as safe as angiography and has a very small complication rate.
The patient is given discharge on the next day after an overnight rest.
A patient gets permanently relieved from arrhythmia by this treatment. He would not require any medicines after successful treatment.
