Yoram Etzion is the head of the cardiac arrhythmia research laboratory and a member of the regenerative medicine and stem cell research center at Ben-Gurion University of the Negev, Beer-Sheva, Israel. He graduated the MD, PhD program of Ben-Gurion University and performed a residency in internal medicine and a post-doc in cardiovascular research in Washington University, St. Louis USA. Currently his main research interests focus on cardiac pacing and electrophysiology and on molecular mechanisms underlying cardiac arrhythmias. A unique methodology developed in Etzion's laboratory enables implantation of cardiac electrodes in small mammals for repeated electrophysiological testing in the freely moving state.
