Synonyms: Faget sign, Sphygmo-thermic dissociation, Sphygmo-thermal dissociation Definition of Relative Bradycardia Physiologically, for each 1 °F rise in body temperature, there is a commensurate increase in the heart rate of 10 beats/min . When temperature elevations are not accompanied by a physiologic increase in the pulse, the patient is said…
