About North Texas Arrhythmia

North Texas Arrhythmia Associates (NTA) was established in March 2010 with the mission to provide the highest quality of care to patients with heart rhythm disorders. At NTA, we adhere to the basic principle that our patients trust us with their lives. We are wholeheartedly committed to honoring that trust, and to that end, we believe that our patients are a vital part of the NTA family.

Following these tenets, we have grown from a small clinic in Denton to an organization with multiple offices throughout North Texas. Our dedicated staff includes two electrophysiologists and a warm, attentive support staff who provide exceptional arrhythmia care for patients in the DFW Metroplex. While our organization has grown, our mission remains the same, and our commitment is stronger than ever to each patient that walks through our doors.
