✦ Synopsis

Changes in respiration and heart rate during sleep states have been recorded by a polygraphic device in healthy preterm infants. Cardiac slowing/bradycardia often coincide with respiratory arrest/apnea. Bradycardia starts early during apneic spells. The incidence of respiratory arrest and cardiac slowing and their simultaneous occurrence is significantly increased by the active or REM sleep state. The physiologic, inhibitory mechanisms of active sleep suggest a neurogenic etiology of episodes of cardiac slowing/bradycardia and/or respiratory arrest/apnea in prematures.
