The aim was the assessment of biventricular pacing (BiV) and right ventricular pacing (RVP) by using plasmatic levels of B-type natriuretic peptide (BNP). This prospective, single blind, intraindividual controlled study which was carried out on 10 patients with chronic BiV.
BNP was obtained over 3 periods on BiV and 1 period on RVP. 20% of patients observed showed a better effect on BNP whilst in RVP as compared with BiV (P 0.05). BNP seemed to be able to identify ventricular pacing with an optimal haemodynamic effect.
