Normally, you can expect the following
- Medicine may be given to help you relax.
- A local anesthetic will be applied to your skin near a vein in your groin, neck or forearm which causes numbness in the area.
- Your healthcare provider will make a needle puncture through your skin and into your blood vessel.
- A small straw sized tube called a sheath will be inserted into your artery or vein.
- Your doctor will gently guide several specialized EP catheters into the blood vessel through the sheath and advance them into your heart.
- Fluoroscopy (a special type of X-ray that is displayed on a TV monitor), is used to help advance the catheters to the heart.
- Your doctor will send small electrical impulses through the catheters to make your heartbeat at different speeds. You may feel your heartbeat stronger or faster.
- Electrical signals produced by your heart will be picked up by special catheters and recorded. This is called cardiac mapping and allows the doctor to locate where arrhythmias are coming from.
- If a certain area of the heart is found to be causing a rhythm problem then your doctor may do an ablation.
- Your doctor will remove the catheter after an EP study is done,
- EP study usually takes 1 to 4 hours.
