The Exercise-Responsive Cardiac Pacemaker


The heart has two properties: rhythmicity and contractility. Rhythmic contractions are initiated by the heart's pacemaker, the sinoatrial node, which lies in the right atrium. If the sino-atrial node fails, or if its electrical excitations are not propagated to the ventricles (the main pumping chambers), they wil still contract rhythmically but at a rate… (More)
