Cardiac Resynchronization Therapy

Cardiac dyssynchrony due to conduction system disease occurs in 20% to 30% of patients with HF and systolic dysfunction. Cardiac resynchronization therapy restores synchronous ventricular activation in patients with HF, reduced LVEF, and left bundle-branch block, or in those requiring chronic ventricular pacing, and may improve LV function, decrease HF hospitalizations, and reduce mortality.
