This course provides cardiologists and electrophysiologists with a comprehensive overview of all aspects of cardiovascular electrophysiology. Well-known experts in each field offer in-depth didactics on state-of-the-art subjects in electrophysiology and device therpay. Each lecture includes, or is followed by, a Q&A with an instantaneous electronic response system. Although this course is designed specifically to prepare the electrophysiologist specialist for the Electrophysiology boards or recertification, it also provides the cardiologist or practicing electrophysiologist with an update on the latest knowledge and advances in electrophysiology. The full spectrum of electrophysiology practice isreviewed, ranging from basic arrhythmia mechanisms and pharmacology, to catheter diagnosis and therapy, and device-based treatments. Educational material are available. There are special sessions designed for those participants taking the Cardiovascular Electrophysiology Certification Boards and Recertification Boards.
