Electrophysiology / Arrhythmia Management


An electrophysiology study (EP study) is a specialized cardiac catheterization that looks at the heart's electrical and conduction system instead of its blood flow. The heart's electrical system controls the beginning of each heartbeat regulates the heart rate. Cardiac arrhythmias are disturbances in the rate or rhythm of the heart's electrical system.


EP studies may lead to the discovery of abnormal or diseased electrical systems.  In these cases, an ablation may be needed to fix an abnormally fast rhythm problem.  During an ablation, energy can be applied to destroy abnormal tissue.  This may be done by freezing (cryoablation) or heating (radiofrequency ablation) tissue.

 

Our electrophysiologists also manage and implant various devices ranging from pacemakers, implantable defibrillators, and biventricular defibrillators and pacemakers.  Pacemakers may be indicated in patients with bradycardia (slowing of the heart rate) and defibrillators may be indicated in patients with weak hearts (cardiomyopathies, heart failure) or in patients with sudden cardiac arrest.  Once these devices are implanted, they are exclusively managed by our dedicated arrhythmia center and electrophysiologists.

 

Lead extractions are procedures where broken, infected, or redundant pacemaker / defibrillator leads are removed from the body.  Often, specialized equipment such as an excimer laser may be needed to remove the leads.  We are currently one of only a handful of practices in Dallas / Fort Worth that offer and have the capability to provide this service.
