Effect of apnea and food reward on the autonomic modulation of heart rate in bottlenose dolphins (Tursiops truncatus) and belugas (Delphinapterus leucas)
1.BackgroundHeart rate (HR) and HR variability (HRV) reflect the autonomic modulation of cardiac activity and are key indicators of physiological state and stress in vertebrates.
