Changes of hemodynamic parameters just after and 1 min after tilting compared to the values before tilting
| Parameter | Just after tilting | 1 min after tilting | ||||||
|---|---|---|---|---|---|---|---|---|
| ΔSV [ml] | ΔCO [l/min] | Δ%SV [%] | %CO [%] | ΔSV [ml] | ΔCO [l/min] | Δ%SV [%] | %CO [%] | |
| HUTT(–) | –3.0 ±38.9 | –0.35 ±4.2 | –8.3 ±58.1 | –0.11 ±0.69 | 12.7 ±33.7 | 0.75 ±3.29 | 0.14 ±0.53 | 0.06 ±0.59 |
| HUTT(+) | 7.3 ±10.9 | 0.44 ±1.4 | 9.5 ±14.5 | 6.6 ±24.6 | 20.2 ±15.8 | 1.28 ±1.45 | 27.1 ±24.1 | 21.2 ±28.9 |
| Value of p | 0.208 | 0.389 | 0.142 | 0.232 | 0.34 | 0.483 | 0.302 | 0.265 |
ΔSV – decrease of stroke volume, ΔCO – decrease of cardiac output, SVi – relative stroke volume decrease in percentage (see text), COi – relative cardiac output decrease in percentage (see text), HUTT(+) – positive tilt test, HUTT(–) – control group without syncope during the tilt test.
