Heart Rhythm Specialists

The physicians at Arrhythmia Associates of South Texas provide a full range electrophysiology services, including complex ablations for disorders such as atrial fibrillation and ventricular tachycardia. We are committed to providing the absolute highest level of patient care and satisfaction and to using some of the most advanced technologies available.

Practice highlights:

  • Our physicians were part of the first team in San Antonio to perform cardiac ablations using the Stereotaxis Robotic Navigation System, which makes complex cases safer than ever before.
  • We have a dedicated cardiac rhythm device nurse and clinic to help manage patients with pacemakers and defibrillators.
  • Offer devices that can be remotely monitored from the comfort of home.
  • Concierge-like service to help make every patient feel comfortable and guide them through the process of scheduling procedures, pre-procedure care, and follow-up appointments.
  • Access to clinical trials for patients who may qualify.

In addition, our physicians are experienced teachers who are committed to educating patients to help them understand their disorder and empower them to make good decisions regarding their management options.

Our Advanced Care

The cardiac electrophysiologists at Arrhythmia Associates of South Texas have the specialized training to diagnose and address electrical problems of the heart and the heart rhythm disorders – or arrhythmias – they cause. It is critical to receive care for arrhythmias not only to improve quality of life, but to prevent serious complications such as stroke, heart failure or even death. We offer:
  • Evaluation and treatment of atrial fibrillation, ventricular tachycardia and other arrhythmias
  • Evaluation and treatment of syncope
  • Management of antiarrhythmic medications
  • Electrophysiology studies
  • Ablations
  • Holter monitors, event monitors, and implantable loop recorders
  • Implantation and management of pacemakers
  • Implantation and management of implanted cardioverter defibrillators (ICDs)
  • Cardiac re-syncronization therapy and biventricular devices
  • Intracardiac echocardiograms
  • Left Atrial Appendage Closure Device
  • Fluoroless Ablation
 

Ablation

Radiofrequency ablation is where one or more flexible, thin tubes (catheters) are guided via x-ray through the blood vessels to abnormal heart muscle tissue. Once there, a burst of radiofrequency energy destroys very small areas of the tissue, which give rise to abnormal electrical signals causing rhythm disturbances.

Holter and Event Monitoring

The 24-hour Holter monitor is an electrocardiographic recording device that utilizes electrodes, which the patient wears for a 24-hour period, including during sleep and exercise. The Holter monitor captures the patient’s entire heart rhythm over a 24-hour period so that it can be analyzed. An event monitor is a similar wearable device that the patient takes home for a period of time. Except rather than continuously recording, the patient manually starts on stops the recoding when he or she suddenly begins to experience symptoms of palpitations or heart racing. The recording of the cardiac event can be transmitted remotely for analysis.

Pacemaker Implantation

Pacemakers are miniature devices that can be implanted underneath the skin to monitor and provide control of a patient’s the heart rhythm. Pacemakers are particularly helpful in patients who suffer from heart rhythms which are abnormally slow. Typically, the pacemaker is placed under the skin of the front wall of the heart below the collarbone. Monitoring of the pacemaker is usually done remotely at home with periodic visits to the cardiologist's office.

ICD Implantation

Implanted cardioverter defibrillators (ICDs) are 99 percent effective in stopping life-threatening arrhythmias and are the most successful therapy to treat ventricular fibrillation, a major cause of sudden cardiac death. An ICD is implanted under the skin near the heart and constantly monitors a patient’s heart rhythm. If it detects a very fast, abnormal heart rhythm, it delivers energy to the heart muscle causing it to beat in a normal rhythm.

Stereotaxis Robotic Navigation for Ablation

Arrhythmia Associates of South Texas features the first cardiac specialists in San Antonio to use the Stereotaxis Robotic Navigation System to perform catheter ablation – a procedure that uses electrical pulses to eliminate troubled heart tissue that may be causing a heart rhythm disorder. During Stereotaxis-guided catheter ablation, a weak magnet field is created around the body. A wire is then more precisely guided to tissue that needs to be removed via ablation with magnets using 3-D imaging.

Fluoroless Ablations

Many imaging techniques used in medicine today, including fluoroscopy (used during heart catheterizations and ablations) involve radiation exposure to patients. Limiting or eliminating radiation whenever possible is always goal. Through the use of advanced 3-D mapping technologies and intracardiac ultrasound, Arrhythmia Associates of South Texas is safely and successfully performing electrophysiology studies and catheter ablations with little or no radiation. This ablation technique can treat atrial fibrillation, atrial flutter, and a variety of supraventricular tachycardias including patients with Wolff-Parkinson-White Syndrome and AV nodal reentrant tachycardia.

About Heart Rhythm Disorders

Arrhythmia Associates of South Texas focuses exclusively on the diagnosis and treatment of the heart’s electrical system, which initiates and coordinates heartbeats. When this system breaks down or malfunctions, the heart rhythm may beat too fast, too slow, or irregularly, and the heart pumps less efficiently. Patients with heart rhythm disorders may experience:

  • palpitations (heart skipping)
  • shortness of breath
  • mild chest discomfort
  • fatigue easily

Some severe heart rhythm disorders can result in passing out (syncope) or even sudden death.

Watchman™ Left Atrial Appendage Closure Implant

An FDA-approved alternative to blood thinners for reducing stroke risk due to non-valvular atrial fibrillation.

If you’ve been diagnosed with non-valvular atrial fibrillation (AFib), it’s important to talk to your doctor about your condition and treatment options. To help get the conversation started, please check out the Watchman site for more information.
