The study and management of abnormal heart rhythms is the core of Electrophysiology, but the successful identification and management of arrhythmias is important to a much wider range of physicians, from trainees in cardiology to general clinical cardiologists to practitioners in other areas of specialization, for example internists. This book is a thorough overview of clinical arrhythmology designed to help general clinical cardiologists and trainees in the fields of clinical cardiology and electrophysiology achieve the competency they need for clinical practice or for further specialization.
