Vasomotor responses to decreased venous return: Effects of cardiac deafferentation in humans

Weisbrod, Cara; Arnolda, Leonard; McKitrick, D.J; O'Driscoll, Gerard; Potter, Kathleen; Green, Daniel


We compared haemodynamic and peripheral vasomotor responses to lower body negative pressure (LBNP) in cardiac transplant recipients who had undergone bicaval anastomoses, involving right atrial deafferentation (-RA), and the conventional procedure in which some atrial baroreceptor afferents remain intact (+RA). We measured mean forearm blood flow (FBF) responses using Doppler/ultrasound during three randomised trials involving 0 (baseline), -20 and -40 mmHg LBNP in 15 transplant recipients (9...[Show more]
