  • Title: Alexithymia, depression and heart rate in candidates for cardiac surgery.
    Author: Bokeriia LA, Golukhova EZ, Polunina AG, Davydov DM, Kruglova MV.
    Journal: Int J Cardiol; 2008 Jun 06; 126(3):448-9. PubMed ID: 17477988.
    Abstract:
    Effects of psychological traits on heart rate (HR) and heart rate variability (HRV) were evaluated in patients awaiting cardiac surgery. Alexithymics demonstrated slowed HR, whereas high cognitive performance was associated with elevated HR in 2-3 days before surgery. Depression negatively correlated with HRV low frequency power. These data are consistent with previous findings of diverse moderate stress effects on HR regulation in cardiologic patients and healthy subjects in accordance to differences in psychological characteristics.
