Educational Resources

The electrophysiology program at Baylor Scott & White Heart and Vascular Hospital – Dallas provides comprehensive evaluation, diagnosis and treatment for patients with abnormal heart rhythms. Physicians on the medical staff specially-trained in cardiac electrophysiology work closely with an experienced team of nurses and nurse practitioners to provide evaluation and treatment using advanced healthcare technology and evidence-based techniques, including medication therapy, catheter-based procedures and surgery.

Baylor Scott & White Heart and Vascular Hospital – Dallas continues to be recognized as a leader in electrophysiology in the Metroplex and the nation because of our focus on successful outcomes, patient satisfaction and our commitment to research. We achieve this through experience – experience that only a high-volume electrophysiology program can provide.

Atrial Fibrillation

Atrial fibrillation originating in the atria, the upper part of the heart, is the most common arrhythmia. This rapid and irregular heartbeat increases a person’s risk of stroke by four to five times.

Heart Rhythm Center

Developed to provide patients with information regarding their arrhythmia, the Center guides patients to a dedicated healthcare provider who specializes in electrophysiology.

Electrophysiology Lab

Learn how specialists diagnosis and treat the heart’s electrical system in our electrophysiology lab.



Arrhythmia is a problem with the electrical system that tells the heart muscle when to contract. This condition causes the heart to have an abnormal beat that is too fast, too slow, and/or irregular. Many arrhythmias do not require urgent treatment, but that same beat can also signal a life-threatening condition. If you or a loved one is experiencing any of these symptoms, it’s important to visit a doctor for evaluation.

It is important to note that not all arrhythmias are accompanied by symptoms. However, some noticeable signs of arrhythmia are:
  • Fluttering in the chest
  • Racing heartbeat
  • Slow heartbeat
  • Chest pain
  • Ongoing fatigue and tiredness
  • Shortness of breath
  • Lightheadedness, dizziness or fainting

Common Types of Arrhythmias

  • Tachycardias: A fast heart rhythm with a rate of more than 100 beats per minute.
  • Bradycardias: A slow heart rhythm with a rate below 60 beats per minute.
  • Supraventricular arrhythmias: Arrhythmias that begin in the atria (upper chamber of the heart).
  • Ventricular arrhythmias: Arrhythmias that begin in the ventricles.
  • Bradyarrhythmia: Slow heart rhythms that may be caused by disease in the heart’s conduction system, such as the sinoatrial (SA) node, atrioventricular (AV) node or HIS-Purkinje network.


Physicians on the medical staff at Baylor Scott & White Heart and Vascular Hospital – Dallas have participated in many of the developments in electrophysiology and continue to be involved in numerous ongoing research projects, including:
  • Atrial fibrillation
  • Congestive heart failure
  • Defibrillation
  • Pacing, including therapies for the management of heart failure, such as cardiac resynchronization therapy (CRT), biventricular pacing, combined CRT and pacing, and combined CRT and defibrillation.

Wired for Life

The Electrophysiology Team is here to provide you with the guidance, encouragement and support you need to live a healthy life with your implantable cardioverter defibrillator (ICD). If you suffer from cardiomyopathy, congestive heart failure or have experienced sudden cardiac arrest, the ICD can be your life vest and has been described by many to be like having a paramedic by your side at all times. Join us for this free workshop designed for you and your loved ones to learn in a group setting how exactly the ICD works.

Class topics include:
  • Cardiac disease
  • Lifestyle changes
  • Shock plan
  • Understanding your device
  • Returning to daily activities
  • Emotional concerns
  • Eating for health
To register for a Wired for Life class or inquiry about the next scheduled class, please call 1.844.BSW.DOCS or visit our Calendar of Events.
