What is the primary purpose of conduction system pacing?

The primary purpose of conduction system pacing is to restore physiological heart rhythm and improve cardiac output. This approach focuses on pacing the natural conduction system of the heart, particularly targeting the His-Purkinje system, to create a more synchronized contraction of the heart muscle. By doing so, it allows for a more effective and efficient movement of blood throughout the body, enhancing overall cardiac function.

When pacing is aligned with the heart's natural conduction system, it helps maintain the physiological sequence of electrical impulses, which is essential for optimal cardiac mechanics. This is particularly important in patients with problems like bundle branch block or other conduction disorders, where traditional pacing may lead to uncoordinated contractions and less effective heart function.

In contrast, other options highlight aspects that do not align with the primary goals of conduction system pacing. Increasing heart rate is not necessarily the main focus, as pacing targets rhythm and synchronization more than just elevating heart rate. Providing constant electrical stimulation does not directly address the restoration of the physiological rhythm, and decreasing blood pressure is not a primary goal since pacing is more about enhancing cardiac output rather than lowering blood pressure.
