MelhodF: Seveaty four matched CaucaSiaa subjects (FM, 38:36; 22-75 years) fire from therapy, were grouped Bccording to their resting blood pnssurcs (BP) using the JNC-VI (1997) classification, into twHmd (NT), high n o d 0, Stage 1 (Em-I) and Stage 2 or 3 hypatcasion (EHT-2B). Continuous heart rate (HR), respiration, BP and synpalhdc activity were rccordtd in the resting state. N e d activity was quantified pcr 100 cardiac beats to allow for d i h c e s in HR.Results: Using ANOVA, d t s from the two methods of sympathdc assessment in the four groups of subjects are illustratcd below, s-MSNA (Fig. 1) and MSNA (Fig.2).
