Electrophysiology studies (EPS) are medical tests used to evaluate the electrical activity of the heart and diagnose abnormal heart rhythms or arrhythmias. The test involves threading thin, flexible wires called catheters through a vein in the groin or arm and into the heart. The catheters are equipped with electrodes that measure the electrical activity of the heart and can also be used to stimulate the heart in order to provoke arrhythmias.
During an EPS, the patient is typically given a mild sedative to help them relax. Once the catheters are in place, the healthcare provider can monitor the heart's electrical activity and stimulate it if necessary to provoke arrhythmias. This allows the provider to diagnose the specific type of arrhythmia and determine the best course of treatment.
EPS is generally considered a safe procedure, but there are some risks associated with it, such as bleeding, infection, or damage to the heart or blood vessels. These risks are rare and can be minimized with careful monitoring and proper technique. The healthcare provider will discuss the risks and benefits of EPS with the patient before the test is performed.
An EPS may be recommended if someone is experiencing symptoms such as palpitations, fainting, or unexplained chest pain, or if they have risk factors for heart disease. It can help diagnose or evaluate conditions such as arrhythmias, heart block, and syncope. EPS can also be used to assess the effectiveness of treatments for arrhythmias, such as medications or implantable devices.
