Resumen
Antecedentes: Se reconocen cada vez más diferencias según el sexo en el pronóstico luego del traumatismo craneoencefálico (TCE). Este artículo examina si dichas diferencias se observan en los valores de la variabilidad de la frecuencia cardíaca (VFC), medida de la cual se halló previamente que se correlacionaba con la gravedad de la lesión y su pronóstico. Materiales, métodos y resultados: Se obtuvieron datos de 16 sujetos que habían sufrido un TCE y de controles apareados por edad y sexo. Los datos incluyeron detalles del traumatismo, registro electrocardiográfico continuo y resultado de la rehabilitación. Se observaron pruebas de disfunción cardíaca en los datos del TCE comparados con sus controles sanos apareados. Además, hubo una sugerencia preliminar de diferencias según el sexo en los parámetros de la VFC del grupo con TCE. Conclusiones: Los hallazgos en este grupo concuerdan con la bibliografía sobre la VFC luego de un TCE. Es recomendable que este trabajo continúe con otros artículos en los que se realicen estudios con una muestra más grande de sujetos con TCE para examinar detalladamente las diferencias según el sexo en los parámetros de la VFC.

Sex Differences In Heart Rate Variability Following Acute Traumatic Brain Injury
Abstract
Background: Sex differences in outcome following traumatic brain injury (TBI) are becoming increasingly recognised. This paper examines whether such differences are found on measures of heart rate variability (HRV), a measure previously found to correlate with injury severity and outcome. Materials, methods and results: Data was collected on 16 subjects with TBI and their age and sex matched controls. Data included injury details, continuous electrocardiograph recordings and rehabilitation outcome. Evidence of cardiac dysfunction was found in the TBI data compared to their matched healthy controls. Furthermore, there was preliminary suggestion of sex differences in the HRV parameters of the TBI group. Conclusions: These group findings replicate previous literature on HRV following TBI. The need to follow-up this paper with larger sample of TBI subjects in order to thoroughly examine sex differences in HRV parameters is recommended.
