Sinoatrial Blocks in Hyperthyroidism Treated with Beta-Blockers: A Case of Paradoxical Treatment

Caterina Chiara De Carlini*, Ester Meles, Roberto Galbiati, Marco Di Sabato, Gaetano Gentile, Andrea Farina and Stefano Maggiolini

We describe an interesting case of a 52 year-old patient affected by thyrotoxicosis crisis, in whom sinoatrial blocks were associated with syncope and treated effi ciently with beta-blockers.

We hypothesized the Bezold-Jarisch refl ex as the mechanism which leads to bradycardia and hypotension with syncope related to prolonged tachycardia.

This hypothesis has not been, to our knowledge, considered in previous studies and offers therapeutic methods, as the patient was not treated with permanent pacing.
