9.Results Plasma levels of BNP (pg / ml) at 10 months were 81.85±17.21 and 54.15±18.16 respectively for VVI(R) and DDD(R) group (P<0.05=. Conclusions Dual chamber pacing is associated lower levels BNP than single chamber ventricular pacing in patients with high-grade AV block. This support the hypothesis that dual chamber pacing confers haemodynamic advantage.
