“…It has been shown that the amplitude of the J-point is inversely proportional to the core temperature and is reversible by gradual rewarming [7,26]. This phenomenon fits with our results of higher prevalence in patients treated with 33°C.…”

“…Normal body temperature is defined as 35.5-37.5 • C in healthy volunteers, although different ranges have been described depending on the site where the body temperature is measured. 1 Body temperature values outside the normal range have been reported to result in substantial changes to the surface electrocardiographs (ECGs), such as heart rate, [2][3][4][5] QRS duration, [4][5][6][7] J-wave prevalence, 4,[8][9][10][11][12] and QT interval duration. 4,6,[13][14][15] Even within the normal range, body temperature has been reported to have an effect on the corrected QT interval (QTc interval).…”

Introduction Previous studies have observed that hypo- and hyperthermia are associated with several atrial and ventricular electrocardiographical parameters, including the corrected QT interval. Preclinical studies have shown that drugs that exert an effect on body temperature also exert an effect on the corrected QT interval. Therefore, increased characterization in healthy humans of the association between the corrected QT interval and body temperature within the normal body temperature range aids in understanding the mechanism behind drug induced corrected QT interval effects. The objective of this analysis was to evaluate the association between body temperature and electrocardiographical parameters in normothermic healthy volunteers. Methods Data from 3023 volunteers collected at our center were analyzed. Only subjects considered healthy after review of collected data by a physician, including a normal tympanic body temperature (35.5–37.5 °C) and in sinus rhythm, were included in the analysis. Subjects were divided into body temperature quartiles for analysis and a linear multivariate model with body temperature as a continuous was performed. Another multivariate analysis was performed with only the QT subintervals as independent variables and body temperature as dependent variable. Results Mean age was 33.8±17.5 years and mean body temperature was 36.6±0.4 °C. Body temperature was independently associated with age (standardized coefficient (SC)=−0.252, P<0.001), gender (SC=+0.208, P<0.001), heart rate (SC=+0.230, P<0.001), J-point elevation in lead V4 (SC=−0.118, P<0.001), and Fridericia corrected QT interval (SC=−0.061, P=0.002). Atrial and AV nodal parameters were not independently associated with body temperature. The effects of temperature on the surface ECG are displayed in figure 1. QT subinterval analysis revealed that only QRS duration (SC=−0.121, P<0.001) was independently associated with body temperature. Conclusion Body temperature in normothermic healthy volunteers was associated with heart rate, J-point amplitude in lead V4 and ventricular conductivity, primarily through a prolongation of the QRS duration. In contrast, atrial and AV nodal ECG parameters were not independently associated with body temperature. Funding Acknowledgement Type of funding source: None

The correlation between the amplitude of Osborn wave and core body temperature

Abstract: The amplitude of the J wave in the admission ECG of hypothermic patients may not accurately predict the core body temperature.
