2. Fig. 1
Profile of 1-min averages of hemodynamic data during head-up tilt from 24 normal women ( • solid error bars) and 16 normal men (open ▴ dashed error bars). The changes in heart rate, systolic and diastolic pressure are expressed as absolute differences from baseline whereas the change in cardiac output, stroke volume and peripheral resistance is expressed as a percent of baseline. Error bars reflect one standard deviation.
