Apresentamos o caso de uma mulher de 76 anos internada ap\u00f3s parada card\u00edaca extra-hospitalar, que foi revertida ap\u00f3s tratamento com desfibrila\u00e7\u00e3o. O eletrocardiograma p\u00f3s-ressuscita\u00e7\u00e3o documentou bloqueio atrioventricular completo, e o ecocardiograma revelou disfun\u00e7\u00e3o ventricular esquerda grave com baloniza\u00e7\u00e3o apical. A angiografia coron\u00e1ria excluiu doen\u00e7a arterial coronariana, e a s\u00edndrome de Takotsubo foi diagnosticada com base nas caracter\u00edsticas cl\u00ednicas e de imagem. O bloqueio atrioventricular persistiu apesar da normaliza\u00e7\u00e3o da fun\u00e7\u00e3o ventricular esquerda; portanto, a parada card\u00edaca foi considerada secund\u00e1ria a uma arritmia ventricular induzida por bloqueio atrioventricular, e um marca-passo, em vez de um cardioversor-desfibrilador implant\u00e1vel, foi implantado. Durante o acompanhamento, o bloqueio atrioventricular completo persistiu, com 99% da estimula\u00e7\u00e3o ventricular observada ap\u00f3s a investiga\u00e7\u00e3o do dispositivo. Este caso corrobora a hip\u00f3tese de que o estresse do bloqueio atrioventricular pode desencadear a s\u00edndrome de Takotsubo, que \u00e9 agravada pela persist\u00eancia de anormalidades de condu\u00e7\u00e3o, apesar da revers\u00e3o dos defeitos ventriculares. Portanto, a implanta\u00e7\u00e3o precoce de um dispositivo card\u00edaco deve ser cuidadosamente considerada caso a caso.<\/jats:p>","DOI":"10.36660\/abc.20250245","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T14:04:31Z","timestamp":1767967471000},"source":"Crossref","is-referenced-by-count":0,"title":["S\u00edndrome de Takotsubo, Bloqueio Atrioventricular Completo e Parada Card\u00edaca: Um Desafio Cl\u00ednico"],"prefix":"10.36660","volume":"122","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9896-7272","authenticated-orcid":false,"given":"Ana","family":"Abrantes","sequence":"first","affiliation":[{"name":"Unidade Local de Sa\u00fade Santa Maria,  Portugal;
