Standard flow sequence Vs. Real-time flow sequence, at rest | -0.58 | -0.58 | -4.71 | 0.994 (p < 0.005) |
Real-time ventricular volume Vs. Real-time flow volume, at rest | -2.04 | -8.29 | 4.21 | 0.988 (p < 0.005) |
Real-time ventricular volume Vs. Real-time flow volume, at 8 W | 0.83 | -4.18 | 5.84 | 0.984 (p < 0.005) |
