Heart-rate and blood pressure measurements allowed analysis of cardiovascular responses (CVRs) to an intermittent pink noise in 9 Type A (coronary prone) and 8 Type B (non-prone) female subjects (Ss). If all Ss are sorted out in sensible, moderately sensible and poorly sensible subgroups, according to similarity in evolution of their heart rates and by completely identifying their heart rate reactivity, results of the analysis do not cross-check those of the behavioral A/B distinction. Although 7 out of 8 B Ss cluster in the moderately sensible subgroup, and although sensible Ss are all of Type A, A Ss are distributed almost equally in the 3 categories, and provide all varieties of CVR responses. Diversity of A Ss for CVR has no relationship with their scores on the Bortner scale.
