Biventricular versus Right Ventricular Pacing in Heart Failure Patients with Atrioventricular Block - The New England Journal of Medicine - 2013

Brief Summary:

In patients with high grade AV block and mild to moderate heart failure, biventricular pacing is associated with a 10% absolute reduction in death, urgent heart failure care and adverse LV remodeling compared with right ventricular pacing, with the difference driven primarily by reduced heart failure hospitalizations and reduced LV remodeling.
