Does biventricular pacing improve outcomes compared to conventional right ventricular pacing in patients with atrioventricular block and left ventricular systolic dysfunction with NYHA class I-III heart failure?
Biventricular pacing is superior to conventional right ventricular pacing in patients with AV block, LV systolic dysfunction, and mild-to-moderate heart failure.
