Do patients with ME/CFS have altered autonomic cardiac regulation (HR parameters) compared to healthy controls?
ME/CFS patients exhibit altered autonomic cardiac regulation, as evidenced by differences in heart rate parameters compared to healthy controls.
The differences in HR parameters identified by the meta-analysis indicate that ME/CFS patients have altered autonomic cardiac regulation when compared to healthy controls. These alterations in HR parameters may be symptomatic of the condition.
Nelson et al. (Tue,) studied this question.
