The California Heart Rhythm Symposium aims to bring together leaders in cardiac electrophysiology (EP) and provide a forum for presenting and discussing the latest advances in this medical subspecialty. The meeting will highlight the basic and clinical mechanisms of cardiac arrhythmias, standard methods for their evaluation and treatment, and new advances in their treatment. The conference will target clinical and basic cardiac researchers in cardiac electrophysiology, clinical electrophysiologists (both academic and private), nurses, technicians, and allied industry professionals working in the EP clinic and/or EP laboratory.
