Join Digital Education Committee Member and podcast host Deep Chandh Raja, MBBS, MD, PhD , and his guests Georgios Leventopoulos, MD, and Muthiah Subramanian, MD, CCDS, CEPS-A, for this week's Lead episode.

This Heart Rhythm article investigates the Bachmann bundle as a target for pacing by using retrograde electrical mapping and correlating findings with underlying myocardial microstructure. The piece provides detailed insights into how Bachmann bundle activation pathways relate to tissue architecture, with implications for optimizing physiologic pacing strategies. These findings may help refine pacing techniques that aim to better mimic natural conduction and improve clinical responses.

Learning Objectives

• Describe the anatomical and electrophysiologic characteristics of the Bachmann bundle and its role in atrial conduction.
• Explain how retrograde mapping and microstructural correlation can identify optimal pacing targets within the atrial conduction system.
• Evaluate the potential clinical implications of Bachmann bundle pacing for achieving more physiologic atrial activation.
