Electrophysiology Study

Your doctor may recommend an Electrophysiology or EP Study because other tests may not have provided enough information about your heart rhythm problems. During an EP Study, your heart rhythm is closely monitored and any changes are studied. An EP Study can help determine exactly what your rhythm problem is and what can be done to control it. A specially trained doctor called an electrophysiologist perfoms the EP Study.

In general, the EP study is performed by doing two basic things:

  • Recording Electrical Signals: Electrode catheters sense electrical activity in different areas of the heart and measure how fast these impulses travel.
  • Pacing the Heart: Electrode catheters can also deliver tiny electrical impulses to pace the heart (cause it to beat). By pacing the heart, doctors can induce certain arrhythmias so that they can be observed in the EP lab.
