Point of Maximal impulse At the apex of the heart (apical HR) - Base is the top of the heart; apex is the bottom. The coronary arteries Originate from the aorta just above the aortic valve - They supply arterial blood to the heart - Receive most of the blood from diastole, when the aortic valve closes. Sinoatrial node (SA node) the primary pacemaker of the heart - initiates electrical impulses at an inherent rate of 60-100 beats per minute. Depolarization sodium ions move into the cell and po...
