A Rare Case of Cephalosporin Anaphylaxis-Induced Reverse Takotsubo.

This case report details an unusual occurrence of reverse takotsubo induced by cefazolin anaphylaxis. While anaphylactic reactions typically manifest with hypotension and bronchospasm, the development of takotsubo is a rare outcome. The patient experienced an episode of cefazolin-induced anaphylaxis during elective shoulder surgery, subsequently developing reverse takotsubo cardiomyopathy (rTTC) during her hospitalization.
