Optimizing conduction system pacing lead placement utilizing the image overlay technique

The His‐bundle has several locations from which conduction system pacing can be achieved. Some locations offer better sensing, thresholds and paced QRS durations. Existing techniques to aid repositioning of an already deployed, but sub‐optimally placed lead, include either simple memory of the initial lead position combined with its observation on an x‐ray review screen or utilizing an additional vascular access and pacing lead with the first lead serving as a real‐time marker (Two‐lead technique). We describe a novel, readily available, cost‐efficient, imaging‐based approach to assist in the re‐positioning of a pacing lead for His‐bundle pacing (the Image Overlay Technique).
