Liebermeister rule
Description
Liebermeister rule: Defining the relationship between pulse frequency and body temperature in fever. In fever, when the body temperature increases by one degree centigrade, the pulse frequency increases by eight beats per minute.
One exception to this rule is Faget sign in Yellow fever
History
Carl von Liebermeister (1833–1901) was a German Physician. Agreed with the ‘exception’ to his rule as defined by the condition Typhoid fever:
Es ist uns nämlich schon seit längerer Zeit aufgefallen, dass im Typhus das Gesetz, dass mit der Steigerung der temperatur die Frequenz des Pulses zunehme, eine Ausnahme erleide insofern, als bei sehr hoher Temperatur die Pulsfrequenz eine relativ geringe ist.
For a long time we have noticed that in typhus provides an exception to the law that the increase in temperature increases the frequency of the pulse, and in typhus, at very high temperatures, the pulse rate is relatively low
