right coronary artery supplies right side of heart and AV node
left coronary artery supplies left side of heart and sinoatrial node
atrioventricular (AV) node synchronizes contractions between the atria and ventricles, damage results in a
heart block
sinoatrial node pacemaker of the heart, controls flow of blood through heart, damage results in
arrhythmias, afib and stroke
effect of coronary artery disease on myocardial fibers decreases O2 delivery to fibers causing damage
cardiac output amount of blood ejected from the heart per minute
4-8 L/min
stroke volume amount of blood ejected per heart beat
60-100 mL/beat
arteries transport oxygenated blood away from the heart
veins transport deoxygenated blood to the heart
capilaries facilitate exchange of nutrients between blood and tissues
body temperature and heart rate relationship as body temp increases, so does HR
as body temp decreases, so does HR
hyperkalemia increased potassium in the blood, decreasing the rate and force of contractions
hypokalemia decreased potassium in the blood, causing arrhythmias
hypercalcemia increased calcium in the blood, causing increased heart rate
hypocalcemia decreased calcium in the blood, causing decreased heart rate
