Respiratory Sinus Arrhythmia and its Association with Pain in Women with Fibromyalgia Syndrome

Objectives To assess the cardiac autonomic control at rest and during the deep breathing test (DBT) and its association with pain in women with fibromyalgia syndrome (FMS). Methods The study included 20 women with FMS and 20 healthy women (control group, CG). The pain was quantified by assessing the...

Description
Summary:Objectives To assess the cardiac autonomic control at rest and during the deep breathing test (DBT) and its association with pain in women with fibromyalgia syndrome (FMS). Methods The study included 20 women with FMS and 20 healthy women (control group, CG). The pain was quantified by assessing the pressure pain threshold (PPT), VAS of pain, and the pain component of the SF‐36 questionnaire. The RR intervals were recorded in the supine position and during the DBT. The heart rate variability (VHR) was measured by methods in the time and frequency domain. Results The group with FMS had abnormal cardiac autonomic modulation at rest and during DBT, compared to CG (P
