Appropriate temperature–pulse relationships
Temperature	Beats/min
41.1 °f.f.s.C (106 °F)	150
40.6 °f.f.s.C (105 F)	140
40.7 °f.f.s.C (104 F)	130
39.4 °f.f.s.C (103 F)	120
38.9 °f.f.s.C (102 F)	120
38.3 °f.f.s.C (101 F)	110

Patient must be an adult, i.e. ≥ 13 years, with temperature ≥ 102 °F. Pulse must be taken simultaneously with the temperature elevation. Patient should be in Normal Sinus Rhythm without arrhythmia, second/third- degree heart block or pacemaker-induced rhythm. Patient must not be on β-blocker medication.
