Dominance in cardiac parasympathetic activity during real recreational SCUBA diving

Abstract: It was already established that exposure to hyperbaric conditions induces vagal-depended bradycardia but Weld study on autonomic nervous system (ANS) activity during self-contained underwater breathing apparatus (SCUBA) diving is lacking. The aim of the present study was to evaluate ANS modification during real recreational SCUBA diving using heart rate variability analysis (time-domain, frequency-domain and […]
