Term
| When does the isovolumetric contractiion end? |
|
Definition
| When the left ventricular pressure exceeds the end diastolic aorta pressure. |
|
|
Term
|
Definition
The pressure at the end isovolumetric contraction. This is when the pressure opens the aortic valve.
between phase 2 and phase 3 of cardiac cycle |
|
|
Term
|
Definition
Volume at the end of phase 1.
after atrial kick completing the end of ventricular filling |
|
|
Term
|
Definition
| Phase three is the ejection fraction |
|
|
Term
|
Definition
• any mechanism that, at constant muscle length, shifts the force velocity curve to the right, has increased contractility (+ dP/ dt)
|
|
|
Term
• Inotropy
• Chronotropy-
• Dromotropy -
Lusitropy
|
|
Definition
the force or energy of muscular contractions
‘heart rate’
the speed of nerve conduction
- the speed of relaxation (- dP/ dt) (opposite of contractility) |
|
|
Term
Ohms Law?
system ohms law
pulmonary ohms law
simplified law |
|
Definition
change in pressure= Q() x R
Aortic pressure- right atrium pressure=COlv X SV
Pulmonary Arery Pressure-Left Atrium Pressure=CO(rv) x PVR(peripheral vascular resistance
AoP/SVR=PAP/PVR |
