Electrophysiologic Study

Electrophysiologic Study

Electrocardiograms are good tests of the heart’s electrical system, but they are brief and can only capture data and activity taking place at the time of the test. Arrhythmias are intermittent and unpredictable so their cause may not be detectable with an EKG alone. An electrophysiologic, or EP, study can provide more information helpful in diagnosing and treating arrhythmias.

During such a test a cardiac specialist will initiate an arrhythmia event and collect information about the flow of electricity.

An EP study can diagnose the source of arrhythmia symptoms, evaluate medication effectiveness in controlling heart rhythm disorder, predict risk of future cardiac events and help assess the need for implantable devices or other treatments.
