What type of patient typically benefits from conduction system pacing?

Conduction system pacing is particularly advantageous for patients who experience persistent bradycardia and atrioventricular (AV) block. In these cases, traditional pacing methods may not adequately restore normal conduction through the heart, leading to inefficient heart function and symptoms related to inadequate cardiac output.

Patients with persistent bradycardia often have a reduced heart rate, which can result from various conditions impacting the heart's electrical conduction system, such as AV block. AV block specifically impedes the normal transmission of electrical impulses from the atria to the ventricles, causing a disconnection in heart function. Implementing conduction system pacing focuses on stimulating the heart's conduction system—particularly the His-Purkinje system—restoring synchronized ventricular activation and improving hemodynamics.

In contrast, patients with chronic hypertension, normal heart rhythm, or high heart rate variability do not typically require conduction system pacing. These conditions may be unrelated to the conduction abnormalities that conduction system pacing addresses, thus making this pacing method unnecessary for those populations.
