Leslie Saxon, M.D., is a Professor of Clinical Medicine at the Keck School of Medicine of USC, specializing in the diagnosis and treatment of arrhythmias in patients with congestive heart failure. After serving as the director of the electrophysiology laboratory and implantable device services at UC San Francisco, Dr. Saxon was recruited to serve as the Chief of Cardiovascular Medicine at USC.

In addition to using state-of-the-art resynchronization devices in patients with arrhythmias, such as modified pacemakers and implantable defribrillators, Dr. Saxon also collaborates with medical device companies to evaluate the latest, most innovative interventional gadgets for patients with difficult-to-treat heart failure.

Dr. Saxon has completed over 75 publications in various medical journals and is an active member of a multitude of organizations, including the American College of Cardiology, the Heart Rhythm Society, The American Heart Association, and the Heart Failure Society of America.

In 2002, Dr. Saxon co-chaired the first Heart Rhythm Society Conference in Cardiac Resynchronization. On October 26, 2007, Dr. Saxon was proud to host the First Annual USC Body Computing Conference, which brought together leading authors and futurists as well as leaders from the fields of medicine, design, entertainment, the FDA, investment banking, and pharmaceuticals for a day of intense discussions about the nascent but exciting field of wireless physiologic monitoring.
