Cardiac catheterization in patients with pre-existent bundle-branch block can induce complete heart block due to catheter-induced block of the opposite bundle branch, as described in 5 patients.

Does cardiac catheterization induce complete heart block in patients with pre-existent bundle-branch block?
Cardiac catheterization of the ventricle opposite to a pre-existing bundle-branch block carries a risk of inducing complete heart block.
The hazard of complete atrioventricular block during cardiac catheterization of patients with pre-existent bundle-branch block is described. A catheter-induced bundle-branch block, during catheterization of the ventricle opposite that which was already the site of bundle-branch block, would produce complete heart block in the form of bilateral bundle-branch block. Five patients in whom this complication occurred are described.
Stein et al. (Tue,) conducted a case report in Pre-existent bundle-branch block (n=5). Cardiac catheterization was evaluated on Complete atrioventricular block. Cardiac catheterization in patients with pre-existent bundle-branch block can induce complete heart block due to catheter-induced block of the opposite bundle branch, as described in 5 patients.
