Supports standby pacing only without routine prophylaxis in pre-existing LBBB; leaves open need for larger prospective confirmation.
Does pulmonary artery catheterization cause new right bundle-branch block or complete heart block, particularly in patients with pre-existing left bundle-branch block?
Prophylactic pacemaker insertion is not recommended before pulmonary artery catheterization in patients with pre-existing LBBB, though standby pacing equipment should be available due to a 3% risk of new RBBB.
