A trifascicular block refers to a conduction block consisting of a right bundle-branch-block plus either :

1. left anterior hemiblock OR

2. left posterior hemiblock plus a 1st degree AV nodal block (not technically a fascicle, but then, "trifascicular" is a misnomer).

The patient is at risk of complete heart-block perioperatively and should be referred to a cardiologist where possible.

If emergency surgery is required, consider how you will manage complete heart block if it develops perioperatively. Ensure transcutaneous external-pacing or transvenous pacing equipment is available in theater. Discuss with cardiologist if time permits for insertion of temporary pacing wire. refl.in/1i #safety
