cardiac function short Flashcards
1
Q
dromotropy
A
conduction velocity
2
Q
frank starling mechanism
A
• Relates sarcomere length/preload (or index – LVEDV/LVEDP) to force of contraction generated (or index – SV)
3
Q
excitation contraction coupling
A
process of electrical stimulus on myocyte converted to mechanical response
4
Q
windekessel effect
A
elastic potential energy stretching the aorta converted to kinetic energy to propel blood in diastole
5
Q
wall stress
A
related to the tension a myocyte must develop in contraction to generate a given ventricular pressure
6
Q
bowditch effect
A
increased HR causes increased inotropy
7
Q
anrep effect
A
abrupt increase in afterload causes modest increase in inotropy
