http://www.or-live.com/mercyHospital/1790 Heart Disease: – Mercy Hospital's Dr. Alberto Interian, medical director of the Arrhythmia Syncope Center, will present an Electrophysiological Study and Catheter Ablation with 3-D Mapping during a live webcast on November 15th at 5:00 p.m. This will be the first time a procedure of this kind is performed live during a web broadcast and simulcast in English and Spanish. An electrophysiology (EP) test or study looks at the electrical system of the heart by recording the electrical activity from within the chambers of the heart. Thin catheters are advanced into the heart through a small tube similar to cardiac catheterization to see if the irregular heartbeat can be reproduced. An EP study allows the electrophysiologist to study heart rhythm disturbances (arrhythmias) in a controlled setting. The procedure is typically performed when a patient has a pre-determined abnormality such as supraventricular or ventricular tachycardia (SVT or...
