Scheme | End-Diastolic Phase | End-Systolic Phase | EF Error (EF = 35 %) | EF Error (EF = 70 %) |
|---|---|---|---|---|
A | 1st Phase after EKG Trigger | Phase when mid-ventricular slice area reaches minimum. | 3.1% | 4.6% |
B | 2nd Phase after EKG Trigger | Â | 2.3% | 3.5% |
C | 1st Phase before EKG Trigger | Â | 3.0% | 4.4% |
D | 2nd Phase before EKG Trigger | Â | 3.4% | 5.1% |
E | Phase of Max Global Volume | Phase of Min Global Volume | 4.7% | 6.4% |
F | Phase of Max Slice Volume | Phase of Min Slice Volume | 7.0% | 8.7% |
G | Aortic Valve Opening | Aortic Valve Closing | -- | -- |
