|
Laplace's Law |
Wall stress = Pressure × Radius ÷ (wall thickness ×2) |
|
|
Preload |
Wall stress at end diastole (av valves closure) , CVP, PWOP, LVEDP |
|
|
Afterload |
Wall stress @ max aortic ejection flow, early systole |
|
|
Frank starling curve |
Pressure, stroke volume vs. volume, LVEDP; left shift, increased contractility, right shift decreased contractility |
|
|
Pressure volume loop |
d, av valves open, d-a, diastolic filling, a, end diastole, av valves closure, a-b, isovolumetric contraction, b, aortic valve open, b-c, ventricular ejection, c, end systole, aortic valve closure, c-d, isovolumetric relaxation |
|
|
End systolic pressure volume relationship |
C, end systole, increased slope → inotropy |
|
|
End diastolic pressure volume relationship |
Increased slope, decreased compliance for filling |
