5th

the coronary arteries are perfused during ________

diastole

end-diastolic blood volume ejected with each heartbeat is known as

postural (orthostatic) hypotension is a sustained decrease of at least 10 mm Hg in systolic BP or 20 mm Hg in diastolic BP within 3 minutes of moving from a lying or sitting to a standing position

false; should be 20 mm Hg systolic and 10 mm Hg diastolic

the patient undergoing nuclear imaging techniques with stress testing should be instructed not to eat or drink anything for at least 12 hours before the test

turbulent blood flow caused by a narrowed or malfunctioning valve is called a _______, which can be heard during auscultation of the heart

murmur

during diastole, the tricuspid and mitral valves are open, allowing the blood in the atria to flow freely into the relaxed ventricles

true

the sinoatrial (sa) node, with an inherent firing rate of 60-100 impulses/min, is considered the primary pacemaker of the heart
