What We Do

A diagnostic electrophysiology study involves inserting thin, flexible, wire-like tools called catheters into blood vessels of the heart through your leg. The purpose is to trigger and record arrhythmias. 

A diagnostic electrophysiology study is done in a monitored environment and is a same day or overnight admission.
