title = "TRANSFER FUNCTION ANALYSIS OF THE AUTONOMIC RESPONSE TO RESPIRATORY ACTIVITY DURING RANDOM INTERVAL BREATHING.",
abstract = "A method is presented for the noninvasive characterization of the frequency response of the autonomic nervous system (ANS) in mediating fluctuations in heart rate (HR). The approach entails computation of the transfer function magnitude and phase between instantaneous lung volume and HR. Broadband fluctuations in lung volume were initiated when subjects breathed on cue to a sequence of beeps spaced randomly in time. Ten subjects were studied in both supine and standing positions. The transfer function, averaged among all the subjects, showed systematic differences between the two postures, reflecting the differing frequency responses of the sympathetic and parasympathetic divisions of the ANS.",
