Key result
Left heart catheterization induces recurrent ventricular standstill via His bundle trauma during bifascicular block.
Why the study?
Ventricular standstill during left heart catheterization due to catheter-related trauma of His bundle connections is a rare complication that requires characterization.

Warrants caution for transient standstill during left heart catheterization in bifascicular block; leaves open need for pre-procedure pacing strategies.
Highlights the risk of catheter-induced ventricular standstill in patients with pre-existing right bundle branch block and left anterior fascicular block during left heart catheterization.
Twidale et al. (1987) studied this question. Left heart catheterization caused repeated ventricular standstill via trauma to His bundle connections in a patient with right bundle branch and left anterior fascicular block.
