Syndrome provides chronic fatigue clue
Postural orthostatic tachycardia syndrome is common in patients with chronic fatigue syndrome and response to standing should be added into the clinical evaluation of the condition, UK research suggests.
A study of 59 patients with chronic fatigue syndrome and 52 controls matched by age and sex found maximum heart rate on standing was 106 patients with CFS, significantly higher than the 98 in controls.
Overall, 27% of patients with CFS had postural orthostatic tachycardia syndrome compared with 9% of the control population.
