What is a key benefit of successful conduction system pacing?

Successful conduction system pacing offers several advantages, among which increased cardiac output and improved heart rate variability are particularly significant. This pacing technique targets the natural conduction pathways of the heart, which promotes more synchronized contractions of the ventricles. As a result, this leads to a more effective pumping action, thereby enhancing cardiac output.

Furthermore, by restoring the heart's intrinsic conduction, conduction system pacing also helps optimize heart rate variability, which is an important marker of autonomic nervous system activity and overall cardiovascular health. Greater heart rate variability indicates a responsive and adaptable cardiovascular system, facilitating better performance during varying physical demands.

In contrast, some of the other mentioned potential benefits, such as a reduction of pacemaker dependency, are advantageous but do not directly address the key benefits of increased cardiac output and improved heart rate variability that are fundamental to the effectiveness of conduction system pacing.
