Over the past two decades, advances in electroanatomic mapping and cardiovascular imaging and innovations in both catheter ablation and device-based interventions have led to an improved understanding of cardiac anatomy, normal electrophysiologic function, and mechanisms behind heart rhythm disorders. Accordingly, describing cardiac structures in terms of their function and relationship to cardiac conduction1 is much more useful to the clinical electrophysiologist than the conventional approach2 of describing the heart in a purely anatomic and geographic fashion. This chapter on electrophysiologic anatomy highlights features of particular relevance in heart rhythm disorders.
