CONTINUOUS PACING DURING LBBAP WITH A LUMENLESS LEAD: A SIMPLIFIED, ZERO-COST SLIDING-CONTACT TECHNIQUE

Left bundle branch pacing with lumenless leads usually requires disconnecting pacing cables during rotation, creating an electrical blind spot during septal advancement. We describe the "sliding-contact" technique, a zero-cost modification enabling continuous real-time monitoring. Retracting the rubber shroud of a standard sterile alligator pacing clip reduces jaw tension, allowing unrestricted lead pin rotation while preserving electrical continuity. In 42 consecutive cases, LBBAP was successfully performed without complications. Beat-to-beat feedback on QRS morphology, impedance, and injury current was maintained throughout rotation, improving procedural precision and safety without specialized equipment.
