Table 3 Heart rate responses

From: Trapezius activity of fibromyalgia patients is enhanced in stressful situations, but is similar to healthy controls in a quiet naturalistic setting: a case-control study

  Mental stress Laboratory relaxation Lowest 5 min, evening
FM patients 76 (8), 58-89b 71 (8), 55-85c 66 (3), 52-78
Controls 76 (7), 64-88d 67 (8), 54-86 65 (3), 45-76

  1. Heart rate (bpm) during mental stress test, laboratory relaxation, and 5-min period with lowest heart rate during evening activities for fibromyalgia (FM) patients and healthy controls.
  2. Values are mean (SD), range.
  3. aIndependent samples t-test; Paired samples t-test: bdifferent from Laboratory relaxation (p=0.001), and lowest 5 min period during evening (p<0.001); cdifferent from lowest 5 min period during evening (p=0.009); ddifferent from Laboratory relaxation (p<0.001) and lowest 5 min period during evening (p<0.001).
