Introduction to clinical electrophysiologic studies.

Clinical electrophysiology is an evolving field of increasing complexity. Electrophysiologic testing is an invasive technique requiring proper patient selection, appropriately trained personnel, as well as suitable facilities and equipment for its optimal application. This introductory chapter has addressed several aspects of clinical electrophysiologic studies. The present and evolving status of clinical electrophysiology in the management of patients with rhythm and conduction disorders is reviewed in further detail in subsequent chapters of this book.
