Abstract
- The study proposes an extension of cardiac baroreflex (cBR) sequence analysis, traditionally performed over spontaneous fluctuations of heart period and systolic arterial pressure, to typify peripheral resistance baroreflex (prBR) from spontaneous variations of peripheral resistances and diastolic arterial pressure. The prBR baroreflex sensitivity (BRS <subscript>prBR</subscript> ) and percentage of prBR sequences (SEQ% <subscript>prBR</subscript> ) were computed along with analogous quantities assessed over cBR (i.e. BRS <subscript>cBR</subscript> and SEQ% <subscript>cBR</subscript> ). The cBR and prBR were typified in healthy subjects at rest (REST) and during light bicycle ergometer exercise at 10 percent of the maximal effort (EXE). Both cBR and prBR were affected by EXE: indeed, BRS <subscript>cBR</subscript> and SEQ% <subscript>prBR</subscript> were significantly reduced. Moreover, while BRS <subscript>cBR</subscript> and BRS <subscript>prBR</subscript> were not significantly associated, SEQ% <subscript>cBR</subscript> and SEQ% <subscript>prBR</subscript> were, and the correlation coefficient was positive. This study suggests that prBR can be typified from spontaneous variabilities along with the more traditional cBR, thus enlarging the possibility of monitoring human cardiovascular control mechanisms.
