An Electrophysiology (EP) Study is a test used to check out the electrical system of the heart. The electrical system of your heart directs how fast or slow your heart beats and determines how it beats. If it is not beating in the right way, it can cause rhythms that may be life threatening. The goal is to find out what treatment will correct the problem.

In some cases medications help control arrhythmias. There are also other treatments for arrhythmias, including:

Other treatments for arrhythmias include inserting pacemakers and implantable cardioverter defibrillators or ICDs. Pacemakers send electrical impulses to the heart to help it pump properly. ICDs are implanted devices that 'watch' your heart and deliver a shock to the heart in the event of an unsafe heart rhythm or arrhythmia. The ICD can make the heart start beating normally again.
