Baroreflex sensitivity by the spectral (BRSα) and the sequences (BRSS) techniques; rate of occurrence of SBP ramps and of SBP-PI spontaneous sequences

Before BD After BD p Value
BRSα(ms/mm Hg)11.2 (8.5)1.7 (0.8)<0.004
BRSS(ms/mm Hg)10.7 (8.6)Not assessed*
Sequences rate (n/h)134 (151)2.4 (3.4)<0.02
SBP ramps rate (n/h)634 (375)772 (346)NS
  • Values are mean (SD).

  • *After BD not enough spontaneous SBP-PI sequences were found to estimate BRSS (see text).
