What is the main goal of conduction system pacing?

The main goal of conduction system pacing is to restore physiological conduction through the heart. This approach focuses on pacing the heart through its natural conduction pathways, particularly targeting the His-Purkinje system. By doing so, conduction system pacing aims to mimic the intrinsic electrical conduction of the heart, leading to improved synchrony of the ventricular contraction.

This method can provide a more natural rhythm as compared to traditional pacing, which often involves pacing from the right ventricle. Restoring physiological conduction helps to maintain better hemodynamics, optimize cardiac output, and reduce the risk of pacing-induced heart failure by ensuring that the heart's electrical signals follow the normal conduction pathway.

Other choices, while they may address aspects relevant to cardiac pacing, do not capture the primary objective of conduction system pacing. For instance, simply increasing heart rate, preventing all arrhythmias, or maintaining a fixed pacing rate differ from the fundamental aim of re-establishing the heart’s natural conduction system through targeted pacing.
