In medicine, the Faget sign — sometimes called sphygmothermic dissociation — is the unusual pairing of fever with bradycardia (slow pulse). (Fever is usually accompanied by tachycardia (rapid pulse), an association known by the eponym 'Liebermeister's rule'.) The Faget sign is named after Louisiana physician Jean Charles Faget, who studied yellow fever in Louisiana.[1][2]
Rapid Pulse Causes
A rapid or fast heartbeat is when your heart is beating faster than normal. A normal heart rate is 60 to 100 beats per minute. Tachycardia is considered a heart rate of greater than 100 beats per minute. If you are exercising, or performing any kind of activity, your heart will normally beat faster.

The normal resting pulse in adults is between 60 and 100 beats per minute. The resting pulse is faster, for example, in febrile patients, anemic or hypovolemic persons, persons in shock, and patients who have taken drugs that stimulate the heart, such as theophylline, caffeine, nicotine, or cocaine.

- Some pneumonias - Legionella pneumonia and Mycoplasma pneumonia
- Drug fever (e.g. beta-blockers,[3] known as the Beta-Faget sign)
Of note, the Faget sign in bacterial infections is consistently associated with bacteria that have an intracellular life cycle.
