Abstract
- Aim: To characterize the Tpeak-Tend, the Tpeak-Tend dispersion and Tpeak-Tend/QT in children and its relationship with clinical variables. Methods: Cross-sectional study in 126 children between 9 and 12 years of the Camilo Cienfuegos School in Santa Clara, Cuba. Clinical and anthropometric variables were obtained to determine their relationship with electrocardiographic parameters: Tpeak-Tend V5, Tpeak-Tend dispersion and Tpeak-Tend/QT ratio V5. In addition, laboratory tests were conducted. Results: Age and systolic blood pressure are associated with an increased probability of having values of Tpeak-Tend/QT V5 ≥75 percentile for both sexes (OR: 1.72, CI 95%: 1.02-2.91; p= 0.043), (OR: 1.08, CI 95%: 1.01-1.16; p= 0.017) respectively. The body mass index and systolic blood pressure are linearly and significantly correlated with the Tpeak-Tend/QT V5 (r= 0.224; p= 0.012) and (r= 0.220; p= 0.014) respectively. Conclusions: The age of the patients and the systolic blood pressure figures are factors that increase the probability of having values of the Tpeak-Tend/QT V5 ≥75 percentile. There was a significant linear correlation between the Tpeak-Tend/QT V5 with the body mass index and the systolic blood pressure. Resumen Objetivo: Caracterizar el Tpico-Tfinal, la dispersión del Tpico-Tfinal y el Tpico-Tfinal/QT en niños y su relación con variables clínicas. Métodos: Estudio transversal en 126 niños entre 9 y 12 años de la escuela Camilo Cienfuegos en Santa Clara, Cuba. Se obtuvieron variables clínicas y antropométricas para determinar su relación con los parámetros electrocardiográficos: el Tpico-Tfinal V5, la dispersión del Tpico-Tfinal y el Tpico-Tfinal/QT V5. Además, se realizaron pruebas de laboratorio. Resultados: La edad y la presión arterial sistólica se asocian con una mayor probabilidad de tener valores del Tpico-Tfinal/QT V5 ≥75 percentil para ambos sexos (OR: 1.72, IC 95%: 1.02-2.91; p= 0.043), (OR: 1.08, IC 95%: 1.01-1.16; p= 0.017) respectivamente. El índice de masa corporal y la presión arterial sistólica están correlacionados de manera lineal y significativa con el Tpico-Tfinal/QT V5 (r= 0.224; p= 0.012) y (r= 0.220; p= 0.014) respectivamente. Conclusiones: La edad de los pacientes y las cifras de presión arterial sistólica son factores que aumentan la probabilidad de tener valores del percentil Tpico-Tfinal/QT V5 ≥75. Existe correlación lineal significativa entre el Tpico-Tfinal/QT V5 con el índice de masa corporal y la presión arterial sistólica.
