Conduction System Pacing for CRT: A Physiological Alternative.

Abstract

There are many factors contributing to the failure of conventional CRT with biventricular pacing, including coronary anatomy and an inability to stimulate diseased tissue. In this paper, we review evolving conduction system pacing (CSP), a physiological alternative to conventional CRT. CSP allows correction of bundle branch block and provides new opportunities to address multiple limitations of conventional CRT. Further studies are required to determine how the techniques are best applied in specific clinical situations.
