Electroanatomical mapping (EAM) has emerged as a valuable tool for guiding conduction system pacing (CSP), enabling precise identification of the His bundle and left bundle branch regions while minimizing fluoroscopy exposure. The concept of the “His cloud” allows three-dimensional visualization of the His bundle course and facilitates accurate lead placement, particularly in challenging anatomies. EAM also provides real-time feedback on pacing effectiveness and ventricular synchrony. Although cost and procedural time currently limit widespread adoption, EAM-guided CSP represents a promising step toward zero-fluoroscopy, anatomically tailored physiological pacing.

摘要

Electroanatomical mapping (EAM) has emerged as a valuable tool for guiding conduction system pacing (CSP), enabling precise identification of the His bundle and left bundle branch regions while minimizing fluoroscopy exposure. The concept of the “His cloud” allows three-dimensional visualization of the His bundle course and facilitates accurate lead placement, particularly in challenging anatomies. EAM also provides real-time feedback on pacing effectiveness and ventricular synchrony. Although cost and procedural time currently limit widespread adoption, EAM-guided CSP represents a promising step toward zero-fluoroscopy, anatomically tailored physiological pacing.
