“…7, a 100% error in an index indicates that the model prediction for that index is off by 1 standard deviation. Therefore, the histogram shows that 18 (2) systemic pressure, minimum (3) and maximum (4) LV pressure, minimum (5) and maximum (6) time derivative of LV pressure, peak left atrial pressure (7), end-diastolic (8) and end-systolic (9) LV volume, stroke volume (10), ejection fraction (11), cardiac output (12), heart rate (13), ejection time (16), peak S/E/A-wave velocities (15)(16)(17), time-velocity-integral of the E-wave (18) and E/A-velocity ratio (19). flow velocities in the atria, ventricles, arteries, and valves) during one heartbeat are presented in Fig.…”
