Association of Dialysate Bicarbonate with Arrhythmia in the Monitoring in Dialysis (MiD) Study.

We observed a lower frequency of RCA with higher DBIC, compared with DBIC of 35 mEql/L, contrary to our original hypothesis, but this association was attenuated in fully adjusted models. Validation of these findings in larger studies is required, with a further need for interventional studies to explore the optimal DBIC concentration.
