Cases Flashcards
1
Q
If there is more of a difference in the temperature of a thermal dilution test, what is happening?
A
Slower flow (lower CO)
2
Q
What is S3 caused by?
A
Snapping of the chordae tendineae in the ventricles (enlargement of ventricle)
3
Q
What is S4 caused by?
A
Overstretching of the ventricles
4
Q
What is the MOA of digoxin?
A
Increases Ca permeability, causing a longer contraction of the ventricular muscle, lowering end systolic volume (thereby increasing SV), and increasing CO
5
Q
When in the cardiac cycle is the coronary circulation perfused?
A
Diastole
