similarly , patients with an isolated abnormal brake index ( n = 6 ) , i.e . with a normal acceleration index and a normal e/i ratio , showed compared with controls an impaired increment in noradrenaline ( 9.53 +/- 1.66 nmol l-1 vs. 18.74 +/- 1.45 nmol l-1 ; p less than 0.01 ) and adrenaline ( 1.41 +/- 0.22 nmol l-1 vs. 2.92 +/- 0.51 nmol l-1 ; p less than 0.05 ) during 80 % of mwc .
