Relative bradycardia presented as a clinical feature of Brucella melitensis infection: A case report

Abstract

Brucellosis, caused by Brucella species, is an infectious disease transmitted through contact with infected animals or their secretions. The clinical disease is characterized by fever and headache. Relative bradycardia is an inappropriate response of heart rate to body temperature, in which the heart rate does not increase proportionally despite a high fever. In this report, we document one case of Brucella melitensis infection demonstrating relative bradycardia. To our knowledge, this is the first report of relative bradycardia in a patient with brucellosis.

Brucella myocarditis with unusual clinical features & abnormal cardiac MRI: A case report

“…The diagnosis of Brucella myocarditis was based on the patient's long history of untreated brucellosis, typical symptoms, myocarditis inflammation on CMR, typical symptoms, and myocardial involvement. The mechanism of cardiac damage from brucellosis is not clear, but it can be caused by the direct effect of the microorganism, local deposits of immunocomplexes, and inflammatory cytokines such as interleukin-6 [5] , [15] .…”
