Which pacing technique is known to minimize pacing-induced cardiomyopathy?

• A. Ventricular pacing
• B. Conduction system pacing
• C. Atrioventricular pacing
• D. Temporary pacing

Answer: (B)

Conduction system pacing is recognized for its ability to minimize pacing-induced cardiomyopathy, which is a deterioration of the heart's function that can occur with traditional pacing techniques. This method involves pacing the heart at specific sites within the conduction system, particularly targeting the His bundle or the left bundle branch.

By activating the ventricles in a more physiologic manner, conduction system pacing allows for a more synchronized contraction of the heart muscle. This synchronization helps to maintain better cardiac function and reduces the adverse remodeling processes associated with traditional right ventricular pacing, where electrical impulses stimulate the ventricles from a point that is often not aligned with the heart's natural contraction sequence.

This technique is particularly beneficial for patients who require long-term pacing, as it helps preserve ventricular function, reduces the risk of heart failure, and improves overall outcomes. Therefore, conduction system pacing is a preferred approach for minimizing pacing-induced cardiomyopathy compared to other pacing techniques that may not consider the heart's natural electrical pathways.
