Description
Yue Bao and co-authors describe an unusual heart tracing in a 2026 case report of a young child. After repair of a hole between the heart's lower chambers, the 3-year-old developed complete heart block plus a right bundle branch block. A pacemaker using left bundle branch pacing, a more natural method favoured in children, was fitted.
During fitting, the pacing lead touched only the surface of the wall between the chambers, without deep fixing. The tracing then showed a right bundle pattern, which the team calls rare and unlike the usual left bundle pattern seen with standard pacing. No matching cases were found in prior reports, so the note alerts pacing teams to the pattern.
