Cardiac Cycld and Valvular Heart Disease Flashcards
1
Q
What place is the diastolic pressure zero?
A
Ventricles
2
Q
What wave of the venous pulse is absent in atrial fibrillation?
A
- a wave
3
Q
Normally the left ventricle pressure is the same of the aortic pressure, in what situation they are different?
A
Aortic stenosis
*left ventricle pressure>aortic pressure
4
Q
What valvular disease leads a left atrial pressure greater than left ventricular pressure during filling phase?
A
Mitral stenosis
5
Q
Impact of decreases contractility in preload and stroke volume
A
⬇️ stroke volume
Slight ⬆️ preload compensatory
6
Q
excessive increase of atrial pressure during systole, what can cause it?
A
Mitral regurgitation
*backflow of blood during ventricular contraction
