Detecting activation of the sympatho‐adrenal axis from haemodynamic recordings, in conscious rabbits exposed to acute stress

Aims:  When assessing sympathetic activation in acute stress, the attention is often limited to the sympatho‐neural axis, whereas sympatho‐adrenal activation, that can only be detected with poor time resolution from the concentration of plasma catecholamines, is often neglected. This study is aimed at reinvestigating the role and the relevance of the sympatho‐adrenal system in acute stress based on the analysis of haemodynamic responses in conscious rabbits.
