Abstract

This paper provides a graphical evaluation of continuous cardiac baroreceptor measurement during a 45-minute 70-degree head-up tilt (HUT) of five groups of subjects suffering the following: chronic fatigue syndrome (CFS), CFS with fibromyalgia (CFS-FM), CFS with postural orthostatic tachycardia syndrome (CFS-POTS), controls with POTS (CON-POTS), and controls (CON). The full duration of the test was 56-minutes, and included supine five-minute baseline and six-minute recovery periods. A comparative time analyses of weighted BRSI averages as well as the combined total number of sequences and ramps for lags 0,1 and 2 is presented.
