Heart Rate Autonomic Regulation System at Rest and During Paced Breathing among Patients with CRPS as Compared to Age-Matched Healthy Controls

Abstract

The increased heart rate and decreased HRV at rest in patients with CRPS suggest a general autonomic imbalance. The inability of the patients to increase HRV time domain values during paced breathing may suggest that these patients have sustained stress response with minimal changeability in response to slow-paced breathing stimuli.
