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.
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
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.
