What is an EP Study and Why is it Done?

An Electrophysiology (EP) study is a specialized test to check the electrical system of your heart and identify the cause of abnormal heart rhythms (arrhythmias). It helps your doctor understand how the electrical signals in your heart work and locate the source of rhythm problems for effective treatment planning.

Why is an EP Study Done?

Your doctor may recommend an EP study if you have:
✅ Fast, slow, or irregular heartbeats (palpitations)
✅ Unexplained fainting or dizziness
✅ History of ventricular tachycardia (VT) or atrial fibrillation (AF)
✅ To assess the risk of sudden cardiac arrest
✅ To evaluate the need for catheter ablation or device implantation (pacemaker/ICD)

An EP study helps in diagnosing the type of arrhythmia and deciding the best treatment, including medication, catheter ablation, or device implantation.

How is an EP Study Performed?

✅ The procedure is done in a cath lab or EP lab under local anesthesia with sedation.
✅ Thin wires called electrode catheters are inserted through veins (usually in the groin) and guided to your heart.
✅ These catheters record electrical signals from inside the heart and may deliver small impulses to study how your heart responds.
✅ The doctor may try to induce arrhythmias safely to locate their origin.

The procedure typically takes 1-3 hours, and most patients return home the same day or after one night of observation.

Is an EP Study Safe?

EP studies are safe when performed by experienced teams, and complications are rare. Your medical team will monitor you closely during and after the procedure.

What Happens After an EP Study?

• Your doctor will explain the results and discuss the next steps.
• You may return to normal activities within a day or two.
• If an arrhythmia is identified, your doctor may recommend medications, catheter ablation, or a pacemaker/ICD depending on your condition.
