The quest for physiological pacing-Does one size fit all?

Abstract

Pacing is an established and ubiquitous treatment of bradycardias and some types of heart failure. The optimal pacing lead position which maximizes cardiac function and minimizes deterioration of ventricular function remains controversial. The desire to achieve a physiological pacing system that mimics cardiac function has led to the investigation of several potential pacing sites. This editorial provides an overview of past and current pacing lead position and summaries the current and future direction of physiological pacing.

Keywords: cardiac pacing; heart failure; physiological pacing; right ventricular pacing; ventricular dyssynchrony.
