What happens during electrophysiology studies? icon plus
You’ll be given a local anaesthetic to numb your groin as this is where the catheter will be inserted. You may also be given a light sedative. To begin the procedure, your consultant will insert a small, flexible tube into a vein at the top of your leg. They will feed very fine wires (catheters) through the tube and guide them to your heart.
Your consultant will then send electrical pulses through the wires to make your heart beat at different speeds. The wires will pick up the electrical signals produced by your heart in response, and from this your consultant should be able to map and locate the arrhythmia. The procedure takes about an hour.

How to prepare for EP studies icon plus
Your consultant will tell you how to prepare. It’s important to let us know if you’re taking any medication as you may need to stop taking it before your test or procedure. You’ll be asked to stop eating and drinking a few hours beforehand. Like all tests and procedures, there may be some risks and side effects involved. Your consultant will explain these to you and answer any questions you have. -
After the procedure icon plus
You should be able to go home on the day of your procedure. Please arrange for someone to travel home with you. You should rest for three to four days after the procedure to allow time for the top of your leg to heal. Your consultant will discuss your results with you, and let you know when you can get back to your usual routines and activities. They’ll also give you advice on medication, exercise, travel, diet and alcohol.
