Controlled breathing at 0 Controlled breathing at 0.16 Hz significantly decreased the contribution of nonneural mechanisms to the HF power of the HRV in healthy controls (○) and patients with CHF (●). Controlled breathing at 0.16 Hz significantly decreased the contribution of nonneural mechanisms to the HF power of the HRV in healthy controls (○) and patients with CHF (●).
