Evaluation of Different Ventricular Pacing Sites in Patients With Severe Heart Failure

Abstract

In patients with severe congestive heart failure, both LV pacing alone and BIV pacing resulted in a similar and significant acute improvement in SBP, PCWP, and V-wave amplitude compared with baseline measurements and RV pacing alone. These results provide a strong basis for initiating long-term studies examining the chronic effects of LV-based pacing in patients with medically refractory congestive heart failure.
