Comparación del sueño ligero y profundo por medio de la variabilidad de la frecuencia cardíaca

Palabras clave: actividad cardiovascular, variabilidad de la frecuencia cardiaca, sueño NMOR, análisis no lineal

Resumen

El análisis de la variabilidad de la frecuencia cardiaca (VFC) permite evaluar de forma no invasiva la actividad cardiovascular. La VFC presenta diferencias entre el sueño MOR y NMOR. Aunque, existen inconsistencias en el procedimiento de evaluación de la VFC en el sueño NMOR, hay estudios que lo dividen en sueño ligero y profundo mientras que otros no lo hacen. Nuestro objetivo fue determinar si había diferencias entre estos dos tipos de sueño en 12 medidas de la VFC. Se obtuvo la polisomnografía de 24 voluntarios sanos durante dos noches consecutivas. Se encontraron diferencias significativas entre ambos sueños en las medidas del dominio de tiempo DENN y LogVFC y en las del dominio no lineal DE2 y α1. Estas medidas se caracterizan por proporcionar indicadores de la variabilidad en el funcionamiento cardiaco. Se concluye que al menos con estas medidas se justificaría la división del sueño NMOR en ligero y profundo.
