Pre-operative prophylactic transvenous cardiac pacing for bifascicular heart block.
Some authorities consider that the combination of right bundle-branch block with left axis deviation (bifascicular block) is not an indication for prophylactic insertion of a pacing generator in patients undergoing non-cardiac surgery. Five patients who developed peri-operative progression of bifascicular block to complete heart block are described. Bifascicular block, together with any other cardiovascular condition, advanced age or surgery in regions that promote vagal stimulation, merit consideration for prophylactic pacing. A cardiological opinion is an essential aspect of the pre-operative preparation of patients with this abnormality.
