Data is presented as the resistance of the chamber as a percentage of the resistance of the coronary artery during which the coronary vascular bed is at rest (R), during light exercise (E1), and during moderate exercise (E2). LAD indicates the Left Anterior Descending, LCX indicates the Left Circumflex and RCA indicates the Right Coronary Artery
