Blood Pressure

diastole to expand; period in the cardiac cycle when blood enters the relaxed ventricles from the atria
systole to contract; period in the cardiac cycle whien the heart is in contraction and blood is ejected through the aorta and pulmonary artery
normotension normal blood pressure
hypotension low blood pressure
hypertension high blood pressure
cardiac conduction SA node -->AV node -->bundle of His-->bundle branches-->purkinje fibers
sinoatrial node the pacemaker, in the wall of right atrium, initiates electrical conduction of the heartbeat, causes atria to contract
atrioventricular node in center of heart, receives and amplifies condution from SA node to bundle of his
bundle of His goes from AV node to right and left bundle branches
purkinje fibers transmit impulses to the right and left ventricles causing them to contract
polarization resting, resting state of myocardial cell
depolarization change of a myocardial cell from polarized to a state of contraction
repolarization recharging of the myocardial cell from a contracted state back to resting
normal sinus rhythm (NSR) regular rhythm of the heart cycle stimulated by the SA node (60-100 bpm)
