What are the AV valves - COR Nurs 324 Cardiac I - Conduction and rhythms
CORRECT ANSWERS tricuspid and mitral
What are the semilunar valves - CORRECT ANSWERS pulmonic and aortic
Cardiac output - CORRECT ANSWERS The volume of blood ejected from the
left side of the heart in one minute.
HR x SV
Stroke volume - CORRECT ANSWERS volume of blood pumped out of left
ventricle during each contraction
Preload - CORRECT ANSWERS volume of blood being returned to the heart
ventricles at the end of diastole
-the stretching of muscle fibers before contraction (think stretch)
Preload is increased in - CORRECT ANSWERS hypervolemia, regurgitation of
cardiac valves, heart failure
Cardiomyopathy - CORRECT ANSWERS disease of the heart muscle, the
myocardium
(Heart can be overstretched in this situation)
Afterload - CORRECT ANSWERS resistance left ventricle must overcome to
circulate blood (think squeeze)
