Rat model data on ANF and autonomic HR responses are hypothesis-generating; leaves open translation to human physiology or therapy.
Does atrial natriuretic factor infusion alter the change in heart rate in response to autonomic stimulation in a rat model?
ANF enhances cardiac parasympathetic effects peripherally, suggesting a potential shared mechanism with acetylcholine in heart rate regulation.
Atchison et al. (1990) studied this question.
