The reasons for this are multiple and include a need to develop an ability to interpret complex elec- trophysiologic patterns, master the technical skills necessary for device implantation and catheter ablation, and incorporate a vast array of indications for treatment of a variety of arrhythmic conditions. This substantial knowledge base and skill set can become an intimidating barrier to acquisition of the more modest goals of the cardiology fellow, a basic understanding of arrhythmic mechanisms and clinical presentations, comfort of knowing which patient to refer or not refer for arrhythmia procedures and why, and an ability to interpret and weigh the recommendations of electrophysiology specialists. This is further compounded by the fact that the current training guidelines in the United States require only 2 months of electrophysiology experience, far too little to reach even modest training goals. In addition, the classic textbooks in electrophysiology are far too dense and complex for the noninitiated or for those interested only in a nonelectro- physiology career. Hence, we have designed a textbook specifi cally for the cardiology fellow faced with these predicaments, deliberately providing material appropriate for the trainee who will pursue a career in general cardiology or one of the nonelectrophysiology cardiology specialties. The topics mirror offi cial training requirements and the text is written for a very well defi ned target audience who will have to advance through certifi - cation e xaminations. The book is meant to be read and its material mastered during the rotations undertaken by cardiology trainees, or for other interested professionals. The contributors are universally recognized for expertise in their subject matter and have enthusiastically joined in an effort to educate future cardiologists. Jonathan S.
