Background: Besides the typical alternate clinical picture, Wallenberg syndrome may be rarely associated with facial pain due to the involvement of the trigeminal nucleus, and sudden death.

Case: We report a case of lateral medullary infarction associated with potentially life threatening intermittent high degree atrioventricular block which occurred in close temporally association with severe facial pain exacerbations. The case required an urgent implantation of cardiac pacing. We hypothesized that the AV-block was triggered by vasovagal response to centrally-mediated pain. However, a direct involvement of the autonomic brainstem network (solitary tract nucleus and dorsal motor nucleus) could not be excluded.

Conclusion: A similar sequence of events might explain at least part of the unexplained sudden deaths that seldom accompany Wallenberg syndrome. This report highlights the importance of continuous cardiac monitoring, in the acute phase of lateral bulbar ischemia, in order to prevent unfavorable outcome.
