Special articleAtrioventricular and intraventricular conduction: Revised nomenclature and concepts☆

Under the organizing chairmanship of the late Hans Hecht, a symposium on Atrioventricular and Intraventricular Conduction was held in Chicago on May 28–29, 1970 under the auspices of the American College of Chest Physicians and the Center for Continuing Education, University of Chicago. After an extended discussion on nomenclature in this area by more than 150 participants, the present authors convened themselves as a self-appointed committee to create a framework for a revised nomenclature.
