Haemodynamic responses to upright tilt during the EF and ML phases
Measures of (A) SBP, (B) DBP, (C) MAP, (D) HR, (E) SV and (F) TPR are given for supine rest and at 5, 10, 20, 30 and 40 min of tilt. Data are presented using the last stable data carry forward method for subjects who experienced presyncope. Error bars indicate the SD. All variables were significantly altered from supine to upright tilt. SBP and MAP were significantly greater during the ML compared to EF phase.
