Cardiac Terms Flashcards
1
Q
Preload
A
-amount of blood returning to right side of heart and the muscle stretch that the volume causes
2
Q
What is released when the heart muscle stretches?
A
ANP
3
Q
Afterload?
A
The pressure in the aorta and peripheral arteries that the left ventricle has to pump against to get blood out
4
Q
The pressure seen in after load is referred to as what?
A
Resistance
5
Q
With HTN is there even more resistance for the left ventricle to pump against?
A
Yes
6
Q
Because of more resistance in after load, what can eventually develop from HTN?
A
HF and pulmonary edema
7
Q
High after load decreases what?
A
CO and forward flow
8
Q
Does High after load eventually wear your heart out?
A
Yes
9
Q
Stroke volume?
A
Amount of blood pumped out of the ventricles with each beat
