Electrophysiology is one of the fastest growing services at the Heart Lung Vascular Institute. Electrophysiologic studies are performed for the diagnosis and treatment of abnormal heart rhythms. The lab is staffed with board certified Electophysiologists, registered nurses, radiologic technologists and cardiovascular technologists, all specially trained in the techniques used in the evaluation and treatment of rhythm disorders.
Treatment of abnormal heart rhythms may require medication, an ablation procedure or an implantable device (pacemaker or cardiac defibrillator). Some patients with congestive heart failure may be treated using a bi-ventricular implantable device (called cardiac resynchronization therapy or CRT). Many of the devices implanted today enable physicians to monitor the patient’s device wirelessly, preventing frequent visits to the physician’s office. These newer devices can alert the physician when there is a problem with the device or when the patient’s heart condition worsens.
Cardiac ablation procedures are used to treat patients with a variety of abnormal rhythms such as supraventricular tachycardia, ventricular tachycardia, paroxysmal atrial arrhythmia’s, atrial flutter and atrial fibrillation (just to name a few). These catheter-based procedures use up-to-date technology to locate and eliminate the source(s) of the abnormal rhythms. They are effective in treating many abnormal rhythms and typically do not require an overnight stay.
In response to a growing population of patients with atrial fibrillation, UT Medical Center’s Heart Lung Vascular Institute launched the region’s first Atrial Fibrillation Center in October 2008. Atrial fibrillation is a serious abnormal rhythm that carries a risk of stroke.
Patients who are interested in an evaluation may request a physician referral or contact our Atrial Fibrillation Center Coordinator at 865-305-6016 to see if they meet the criteria for self-referral.
