Summary:Ten volunteer subjects each attended four training sessions of 1 hr, during which they were instructed to raise or lower blood pressure. They were provided with immediate analogue feedback of pulse wave velocity from a PDP-12 computer, and successful performance was rewarded with money. Significant differences in PWV between Increase and Decrease conditions were produced, the mean divergence in the final trial being equivalent to 11 mm Hg. These changes were accompanied by adjustments in heart rate and respiration rate, and did not improve with repeated sessions—indeed on some measures deterioration in performance was observed. Neither analysis from the initial baseline nor from the pre-trial level, appears to reflect the precise effects of feedback. Different methods of assessment are discussed, together with the use of PWV as a measure of blood pressure in such experiments.
