Mobitz Type-2 Heart Block After a Bee-Sting
1Cardiology, University of North Carolina, Chapel Hill, USA.
Abstract:
We report the case of a patient who developed symptomatic bradycardia and Mobitz type 2 heart block one week after a single bee sting. This required implantation of a permanent pacemaker. The patient had no significant past medical history, and previous electrocardiogram (ECGs) did not show heart block or bradycardia. He has been physically active in the past and denied any such symptoms. We presume bee sting to be the cause of his symptomatic bradycardia and heart block. We also think that his heart block was reversible and has since resolved, as his most recent device check showed minimal V-pacing. The cause of his heart block can be either Kounis syndrome or Apamin-mediated calcium channel block. A detailed discussion is done separately.
