Use of heart rate and heart rate variability in decision making research

Beranek, C.*, Halfmann, K., Kurczek, J., & Hedgcock, W. (2014, March). Use of heart rate and heart rate variability in decision making research. Poster presentation at the Tippie Research Fair, Iowa City, IA. • The autonomic nervous system controls non- conscious func.ons like breathing, heart beat, and diges.on. • It can be divided into the sympathe.c nervous system (SNS) which excites and the parasympathe.c nervous system (PNS) which calms. (4) • Combined, the SNS and PNS control heart rate variability, the change of .me between successive heart beats. (1) • Using an ECG (electrocardiogram) we can non- invasively observe PNS ac.vity (HR and HRV).
