RIGHT VENTRICULAR (RV) apical pacing frequently worsens ventricular dyssynchrony.
Data suggest that RV apical pacing is associated with an increase in hospitalizations
for heart failure (HF) and atrial fibrillation (AF).

After cardiopulmonary bypass (CPB), a number of patients may exhibit symptoms of
heart failure with interventricular and intraventricular dyssynchrony. Patients may
require atrioventricular (AV) pacing in the immediate post-CPB period. RV pacing may
result in worsened septal dyssynchrony and hemodynamic profiles. The authors report
a case in which early implementation of biventricular pacing (BiVP) in the post-CPB
period resulted in the resolution of septal dyskinesia and an immediate improvement
in hemodynamic function.Key words
