Implication

Simultaneous proximal bundle activation in rate-related LBBB; leaves open generalizability beyond this single case report.

Structured PICO

P
Population
13 patients (7 without conduction defects, 3 with His and left bundle branch recorded, and 3 with rate-related left bundle branch block)
I
Intervention
Electrode catheter recording of His, right bundle branch, and left bundle branch potentials, with coupled atrial pacing
O
Outcome
Conduction intervals (H-Q, LB-Q, RB-Q, H-LB, H-RB, LB-RB) and onset of ventricular activationsurrogate

In humans, the proximal left and right bundle branches are typically activated simultaneously, and unilateral bundle branch block does not significantly delay the onset of ventricular activation.
