The antifibrillatory mechanism of biatrial (BI) pacing has not been fully elucidated. We investigated the role of a haemodynamic mechanism in eight patients implanted with a BI pacemaker (Chorus RM) by comparing changes in mitral Doppler flow and atrial and B-type natriuretic peptide levels (ANP, BNP) with BI pacing compared with sinus rhythm and right atrial (RA) pacing.
