Faget sign
From Wikipedia, the free encyclopedia
In medicine, the Faget sign is the unusual constellation of fever and bradycardia (a slow pulse). It is often seen in yellow fever.
Fever is usually accompanied by tachycardia (a fast pulse), an association known by the eponym Liebermeister's rule.
Faget sign is also seen in:
- Typhoid Fever
- tularaemia
- brucellosis
- Colorado tick fever
- Some pneumonias - Legionella pneumonia and Mycoplasma pneumonia
- Drug Fever (eg. Beta-Blockers,[1] known as the Beta-Faget sign)
It is named after Jean Charles Faget, who characterized it in 1859.[2][3]
