INTRODUCTION: The corrected QT interval (QTc) is crucial to evaluate cardiovascular health in neonates, and its alteration may indicate risks of arrhythmias. This study compares QTc variation in neonates born at sea level and at altitude, exploring how environmental conditions, such as altitude, could influence the duration of this interval. OBJECTIVE: To determine the variation in the characteristics of the QTc interval in newborns born at altitude compared to those born at sea level, 2024 MATERIALS AND METHOD: Exploratory study, observational and cross-sectional design. The information was collected with a data form for the variables of interest, the instrument was applied in two reference health care centers in locations at sea level and at high altitude. The information was processed using the statistical software SPSS v27.0 for univariate and comparative analysis RESULTS: In the research, a predominantly male participation was observed in both samples, with 55% and 57% males for the populations at sea level and at altitude, respectively. Both samples were characterized by having full-term neonates, with weight and size appropriate for gestational age and normal oxygen saturation. Regarding the QTc interval, the results showed differences between the two populations. In neonates born at altitude, the median QTc interval (Bazzet) was 406 ms, while in the sample at sea level it was 383 ms. The calculations with the Fridericia and Hodges formulas also showed variations between both populations, with slightly higher values in those born at sea level. CONCLUSION: It was found that there are significant differences in the QT values using any of the three methods (Bazzet, Fridericia and Hodges) between newborns born at altitude and at sea level, where the former have higher values (p < 0.05)
