Determination of relative bradycardia. Reproduced with permission from Cunha, 2000 [46]

Inclusive criteria:

(1) Patient must be an adult (2) Temperature ≥ 102°F (3) Pulse must be taken simultaneously with the temperature elevation Exclusive criteria:

(1) Patient has no arrhythmias, 2nd/3rd degree heart block, or a pacemaker-induced rhythm (2) Patient must not be on β-blocker medications, diltiazem verapami

Appropriate temperature-pulse relationships:

Temperature	Beats/min
41.1 °C (106 °F)	150
40.6 °C (105 °F)	140
40.7 °C (104 °F)	130
39.4 °C (103 °F)	120
38.9 °C (102 °F)	120
38.3 °C (101 °F)	110
