recordings collected under conditions, respectively, implying a complex interaction between the SAN and the autonomic nervous system in determining HRV . Our approach will enable standardization and reproducibility of BRV analysis in mammals. Different trends were found between beating rate and BRV or HRV in isolated SAN tissue vs. recordings collected under in vivo conditions, respectively, implying a complex interaction between the SAN and the autonomic nervous system in determining HRV in vivo.The extensive involvement
