What are the risks of ep study on heart?

Risks are low: I perform ep studies and they are generally safe. The most common risk is local bleeding as the doctors will need to access the vein in your groin (femoral vein) in order to place the catheters within your heart. The bleeding is usually very minimal and not dangerous. Serious complications such as infection, internal bleeding, heart attack, heart block needing pacemaker, or stroke are.

A few: Stimulation of severe rhythm problems; bleeding from the catheter insertion site(s); damage to the vessel at the catheter insertion site(s); rarely, infection of the catheter site(s); rarely, perforation of the heart. There is also some radiation exposure. In skilled hands, these risks are very low.
