Based on the concept that the cardiac muscle is differentiated mainly for excitation, conduction and contraction, cardiology has for many years focused mainly on the ventricles, with comparatively little attention to the atria. However, demonstration of the heart as an endocrine organ and recognition of its role in the regulation of volume and electrolyte homeostasis via the release of the atrial natriuretic peptide (ANP), have led to renewed interest in the atria and emergence of a new research direction, atrial cardiology.
