Multisite Left Ventricular Pacing in Cardiac Resynchronization Therapy

Card Electrophysiol Clin. 2022 Jun;14(2):253-261. doi: 10.1016/j.ccep.2021.12.003. Epub 2022 May 24.

Abstract

Cardiac resynchronization therapy (CRT) is an established treatment of patients with heart failure with reduced ejection fraction and prolonged ventricular depolarization on surface electrocardiogram. Although patients' characteristics, such as their type of cardiomyopathy and the morphology and width of their baseline QRS complex, have been associated with CRT response, these features are not modifiable. Left ventricular multisite pacing has been proposed and tested as a tool to improve response to CRT and positively impact patient outcomes. This article reviews the published literature on left ventricular multisite pacing, with focus on the results of recently presented or published clinical trials.
