Cardiac Electrophysiology

When a patient develops a heart rhythm condition, cardiologists from the Yuma Regional Medical Center electrophysiology team are ready.  With their special training, excellent experience and advanced treatments, they care for adult patients with:

  • Atrial fibrillation
  • Atrial flutter
  • Arrhythmias
  • Ventricular tachycardia
  • Supraventricular tachycardia
  • Heart failure
  • Bradycardia
  • Syncope

Our cardiac electrophysiologists provide:

  • Diagnostic electrophysiology studies
  • Cardiac resynchronization therapy
  • His bundle pacing
  • Left bundle branch pacing
  • Radiofrequency ablation
  • Left atrial appendage closure
  • Cryoballoon ablation
  • Defibrillator and cardiac device implantation

Diagnostic Electrophysiology Studies

If you are experiencing an abnormal heartbeat, your cardiovascular specialist may recommend an electrophysiology (EP) study. This test records the electrical activity in and electrical pathways of your heart. It will also help your doctor determine the cause of your heart rhythm disturbance. Together, you can decide on the best treatment for you.

If you are a candidate for an implantable cardioverter defibrillator (ICD) or pacemaker, an EP test helps determine which device is best for you. Future studies may be scheduled to monitor the effectiveness of your device.

An EP study can also diagnose patients who may benefit from cardiac ablation, a procedure used to treat rapid or irregular heartbeats. Cardiac ablation uses radiofrequency energy (similar to microwave heat) to restore the heart’s regular rhythm by destroying a small heart tissue area that is causing the irregularities.

How to prepare for your EP study:
  • Ask your doctor what medications you are allowed to take as you prepare to take the test. Your doctor may ask you to stop certain medications one to five days beforehand. If you have diabetes, ask your doctor how you should adjust your diabetes medications.
  • Do not eat or drink anything after midnight the evening before the EP study. If you must take medications, take them only with a small sip of water.
  • Ask a friend or family member to drive you to your appointment. If you are released to return home the same day, you will need someone to drive you.
  • Wear comfortable clothes when you come to the hospital. You will change into a hospital gown for the procedure. Leave all jewelry or valuables at home.

What to expect during your EP study:

At the start of the EP study, you will lie on a bed and the nurse will insert an intravenous (IV) line into your arm or hand. You will be given a drug through your IV to relax you and make you drowsy, but it may not put you totally to sleep. Your nurse will also connect you to several monitors.

An electrophysiologist will then perform the EP study by inserting several catheters that will be used to evaluate the electrical activity in your heart. You may also be given several drugs to assist in this process.

After the procedure, you will need to lie down for several hours. Your doctor will tell you if you can go home or if you must stay in the hospital to continue your recovery.
