An electrophysiology (EP) study is a test that records the electrical activity and the electrical pathways of the heart. This test is used to help determine the cause of a heart rhythm disturbance and the best treatment to correct the condition. During the EP study, the electrophysiologist will safely reproduce your abnormal heart rhythm and then may give you different medications to see which one controls it best or to determine the best procedure or device to treat your heart rhythm.

An electrophysiology study is used:

  • To determine the cause of an abnormal heart rhythm.
  • To locate the site of origin of an abnormal heart rhythm.
  • To decide the best treatment for an abnormal heart rhythm.

The Mercy Heart Center has a fully-equipped electrophysiology lab to serve patients in a comprehensive setting with the latest technology and highly trained and experienced staff.
