Cardiovascular Physiology Flashcards
1
Q
site of greatest resistance
A
arterioles
2
Q
systolic - diastolic pressure
A
pulse pressure
3
Q
mean arterial pressure
A
(2 x DBP) + SBP divided by 3
Normal value: 70-100
indicates that there’s enough consistent pressure in your arteries to deliver blood throughout your body
4
Q
Difference of Mobitz 1 and 2
A
Mobitz 1 - gradual prolongation of PR
Mobitz 2 - constant PR interval
5
Q
Inotropic effect
A
Contractility
