Does left ventricular or biventricular pacing improve systolic function and energy cost in patients with dilated cardiomyopathy and left bundle-branch block?
Left ventricular or biventricular pacing acutely improves systolic function and lowers energy cost in DCM patients with LBBB, suggesting value for treating basal dyssynchrony.
Ventricular resynchronization by left ventricular or biventricular pacing/stimulation in DCM patients with left bundle-branch block acutely enhances systolic function while modestly lowering energy cost. This should prove valuable for treating DCM patients with basal dyssynchrony.
Nelson et al. (Tue,) studied this question.
