  • The table includes the pooled data with all pacing modes and VV-delays. Values are mean±SD. Significance are based on linear mixed models with estimated marginal means not presented in the table. Abbreviations: AV-delay: atrioventricular-delay, VV-delay: Interventricular delay.

  • *P<0.01 compared with the other groups.
