Comparison of the Acute Hemodynamic Effect of Right Ventricular Apex, Outflow Tract, and Dual‐Site Right Ventricular Pacing

Abstract

Dual-site right ventricular pacing in comparison to RVA pacing improved cardiac systolic function. RVOT appeared to be more advantageous than RVA pacing in patients with impaired, but not in those with preserved left ventricular function. No clear hemodynamic benefit of DuRV in comparison to RVOT pacing in patients with impaired systolic function was observed.

Heart failure and right ventricular pacing – how to avoid the need for cardiac resynchronization therapy

“…It has been proposed that the adverse effects of RV pacing could be limited by choosing an alternative pacing site in the right ventricle. This led to the development of septal pacing which although promising in observational studies, did not avoid the hemodynamic effect of RV pacing [61], prevent adverse LV remodeling [62,63,64,65] or heart failure events [66] in randomized, controlled studies. These studies are further limited by not employing optimal RV pacing avoidance programming in either arm [9].…”
