Waller BF, Gering LE, Branyas NA, Slack JD. Anatomy, histology, and pathology of the cardiac conduction system: Part I. Clin Cardiol. 1993;16(3):249-52.
Normal anatomic and histologic features of the sinus node, atrial myocardium, and interatrial conduction of the cardiac impulse are reviewed. The controversy surrounding atrial conduction via specialized atrial cells versus specific internodal tracts (between sinus and atrioventricular nodes) is discussed.
