FAGET SIGN

The Faget sign — sometimes called sphygmothermic dissociation — is the unusual pairing of fever with bradicardiya (slow pulse). (Fever is usually accompanied by tachycardia,  (rapid pulse), 

Faget sign is often seen in:

• yellow fever
• typhoid fever
• tularemia
• brucellosisi
• colorado tick fever
• Some phnemonias - legionella pneumonia and mycoplasma pneumonia
• Drug Fever (e.g. Beta-Blockers,^[3] known as the Beta-Faget sign)

LIEBERMEISTER RULE

hai guys!!

Liebermeister's rule -
concerns the increment ratio between an adult individual's cardiac frequency and temperature when in fever.

Each Celsius grade of body temperature increment corresponds to an 8 beats per minute increase in cardiac frequency.

An exception to this rule by creating a relative bradycardia is known as Faget sign (pulse-temperature dissociation)
