Electrophysiology (EP) Study: What to Expect at Home

If the doctor gave you a sedative:

• For 24 hours, don't do anything that requires attention to detail, such as going to work, making important decisions, or signing any legal documents. It takes time for the medicine's effects to completely wear off.

• For your safety, do not drive or operate any machinery that could be dangerous. Wait until the medicine wears off and you can think clearly and react easily.

Do not do strenuous exercise and do not lift, pull, or push anything heavy until your doctor says it is okay. This may be for several days.

Ask your doctor when it is okay to have sex.

You can eat your normal diet. If your stomach is upset, try bland, low-fat foods like plain rice, broiled chicken, toast, and yogurt.

Drink plenty of fluids (unless your doctor tells you not to).

Your doctor will tell you if and when you can restart your medicines. You will also get instructions about taking any new medicines.

If you stopped taking aspirin or some other blood thinner, your doctor will tell you when to start taking it again.

Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.

For 1 or 2 days, keep a bandage over the spot where the catheter was inserted. The bandage probably will fall off in this time.

Put ice or a cold pack on the area for 10 to 20 minutes at a time to help with soreness or swelling. Put a thin cloth between the ice and your skin.

You may shower 24 to 48 hours after the procedure, if your doctor okays it. Pat the incision dry.

Do not soak the catheter site until it is healed. Don't take a bath for 1 week, or until your doctor tells you it is okay.

Watch for bleeding from the site. A small amount of blood (up to the size of a quarter) on the bandage can be normal.

If you are bleeding, lie down and press on the area for 15 minutes to try to make it stop. If the bleeding does not stop, call your doctor or seek immediate medical care.

You passed out (lost consciousness).

You have symptoms of a heart attack. These may include: After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
