What is a common indication for conduction system pacing?

Conduction system pacing is often indicated for patients with atrioventricular (AV) block. This is a serious cardiac condition where the electrical signals from the atria to the ventricles are disrupted, leading to a slower heart rate or even complete heart block. In such situations, traditional pacing methods may not provide optimal outcomes, as they can lead to asynchronous ventricular contraction and reduced cardiac efficiency.

Conduction system pacing, particularly using techniques such as His bundle pacing and left bundle branch pacing, aims to restore more physiological conduction to the ventricles. By targeting the conduction system directly, these techniques help maintain synchronization between atrial and ventricular contraction, improving hemodynamic performance and potentially reducing the risk of heart failure symptoms associated with inefficient pacing.

The other conditions listed, such as chronic hypertension, tachycardia, and atrial fibrillation, may not directly benefit from conduction system pacing in the same way that AV block does, as they primarily involve different mechanisms of cardiac function and rhythm management. Thus, atrioventricular block stands out as a primary indication for implementation of conduction system pacing.
