Reply To: More ECGs for thoughts
Sorry for the delay in replying, I hope that you have had a good Xmas.
Yes, RBBB has been associated with MMVD and many other disease processes in dogs, but the mechanism is unclear. RBBB does not require treatment, but I have seen dogs progress to complete AV block after being diagnosed with MMVD and RBBB so it is worth keeping an eye on them. We presumed in that dog that it had conduction system disease that eventually degenerated and required pacemaker implantation.
Happy New Year 🙂
