Q
A
- A’ is normal single ventricular contraction
- ‘B’ shows increasing preload with constant contractility and afterload
- ‘C’ shows increasing afterload with constant preload and contractility
- ‘D’ shows increasing contractility with constant preload and afterload
ESP= End systolic point; EDP= End diastolic point

Q
A
- A=normal,
- B= mitral stenosis,
- C= aortic stenosis,
- D= mitral regurgitation (chronic),
- E= aortic regurgitation (chronic)
13
Q
A
-
Point B
- Beginning of contraction
- Heart is biggest as it gets
- Shows EDP/EDV relationship
- Shows LVEDV. Pressure is fairly low
- Indicates compliance; how easily ventricle takes in blood without significant rise in pressure
-
Point D
- Ventricle start relaxing
- Ca++ is releasing from troponin and going back to sarcoplasmic reticulum
- Shows ESP/ESV relationship
- ( or ) shows regurgitation
