Non-Contact Cardiac Mapping Has Arrived

Approximately three million people in the United States suffer from some form of supraventricular tachycardia (SVT). Many of these patients suffer from complex forms of this arrhythmia, resulting from multiple points of origin in unpredictable locations in the heart.
Generally, the ability to adequately diagnose these complex tachycardias has been limited by the capability of conventional technology. Diagnostic contact catheters have frequently produced an insufficient amount of data to effectively locate, diagnose and facilitate treatment of these types of complex tachycardias.

Spotlight Interview: Morristown Memorial’s EP Lab

In the last nine years, the cardiac rhythm management program at Morristown Memorial Hospital has grown from one lab with a single cardiac electrophysiologist and three full-time staff members to a full service arrhythmia management team, comprised of three board certified electrophysiologists, two full-time technologists, seven nurses and two office staff members. In addition, we work with a full-time cardiac research nurse coordinator and three additional research nurses.

At our facility, we perform comprehensive electrophysiology studies, radiofrequency ablations for both ventri



Spotlight is on Electrophysiology

EP Lab Digest is kicking off this inaugural issue at a pivotal time period in the field of electrophysiology. Our Vice President, Mr. Richard Cheney, recently received an implantable cardioverter-defibrillator for a non-sustained ventricular tachycardia, coronary artery disease and left ventricular dysfunction. His recent medical trials and tribulations have made it into the front page of the New York Times and other renowned newspapers to demonstrate the universality of implantable devices. He was treated quickly and appropriately by the George Washington Electrophysi-ology Team and receive



The Value of Education in the EP Lab

For those of us who have worked in the field of medicine, the advances of science have provided us with new and improved ways to heal and repair the body. The changes that we deal with are sometimes small improvements to an established process, while at other times they are monumental breakthroughs that restructure the way we approach the world of medicine. Dealing with major alterations in the workplace can be one of the most difficult aspects medical professionals must face.



When Did NASPE Get So Big?

I walked out of a presentation at this year s 22nd Annual North American Society of Pacing and Electrophysiology s Scientific Sessions, I heard someone say, when did NASPE get so big? This made me think, how did we come this far, this fast, and what does the future hold for the field of Electrophysiology?



Use of Microvolt T-wave Alternans Testing in Clinical Practice to Reduce Sudden Cardiac Arrest and Death

Microvolt T-Wave Alternans (MTWA) is a new non-invasive method for identifying patients at increased risk of cardiac arrest and sudden cardiac death from ventricular arrhythmias. MTWA can be measured during a routine exercise stress test during pharmacologic stress or during cardiac pacing. MTWA has been successfully applied to patients both with and without coronary artery disease. Its clinical performance compares favorably with that of other non-invasive risk stratifiers and invasive electrophysiologic study (EPS). The event rate during follow-up among patients who test MTWA-positive is com



Spotlight Interview Walter Reed Army Medical Center

What types of procedures are performed at your facility? Approximately how many are performed each week? What complications do you find during these procedures?
Joan: The cardiac catheterization lab performs diagnostic and interventional coronary procedures to include angioplasty, stenting, rotational atherectomy, directional coronary atherectomy, the Cardioseal atrial septal closure device, peripheral and carotid artery stenting, and Angiojet. The electrophysiology lab performs EP studies and radiofrequency (RF) ablations on AVNRT, atrial flutter, AVRT, ectopic atrial tachycardias, and vent
