What is an electrophysiology test?

Never had it done.

But here is University of California San Francisco procedure.

It is like the angiogram I had last year. Usually they’ll keep the patient around for a few hours after the procedure to make sure the catheter entry point heals and doesn’t bleed. And, they will most likely require someone to pick up the patient to drive them home.

Be aware that if they find a blockage, they might insert a stent, which would mean an overnight stay. That’s what happened to me.

@zenvelo is partially correct, although it does not involve a blockage and a stent. EPS studies are done for pepole with electrical disturbances of the heart such as atrial fibrillation. What it does is fine ths source of the disturbance and destroy that little area to help cure the electrical disturbance.

The best thing to do is to call the hospital for the exact information you need.
My husband had what Caravanfan is talking about. Which is called a
Cardiac Ablation This is not part of the test your husband is having. It is a procedure that may be done separately.
