| الوصف: | The aim of this paper is to analyze the autonomic behavior mediated by the baroreceptor response to an orthostatic maneuver (OM) in hypertensive and non-hypertensive subjects. The heart rate (HR) was obtained in 65 subjects (32 hypertensive and 33 non-hypertensive) using a frequency meter polar watch, before and after an OM (sudden standing). The R-R intervals were transformed into a heart rate, temporal series, and interpolation was applied due to a lack of heart rate periodicity. Sampling at 10Hz was performed, and a band-pass filter was applied followed by 1 Hz subsampling. The results showed an increase in sympathetic activity in the hypertensive group that did not occur in the non-hypertensive group after the OM (∆%=59.84%, P<0.01). For the parasympathetic results, decreases were found only in the hypertensive group and not in the non-hypertensive group after the orthostatic intervention (∆%= -43.4%, P<0.001). Increases in both groups were observed for the sympathovagal balance (hypertensive: ∆%= 45.63%, p=0.004; non-hypertensive: ∆%= 67.08%, p=0.013). The results showed increased sympathetic activity in contrast to a decreased parasympathetic response for hypertensive individuals after an OM. ; El propósito de este trabajo es analizar el comportamiento autonómico mediado por la respuesta barorreceptora a una maniobra ortostática (MO) en sujetos hipertensos y no hipertensos. La frecuencia cardiaca (FC) fue obtenida en 65 sujetos (32 hipertensos y 33 no hipertensos) usando un monitor polar de frecuencia cardíaca, antes y después de una MO (al ponerse de pie súbitamente). Los intervalos R-R fueron transformados en series temporales (ST) de frecuencia cardíaca. Se aplicó interpolación debido a una falta de periodicidad en la ST de FC. Un muestreo de 10 Hz fue realizado, adicionalmente un filtro pasa banda seguida de un sub muestreo a 1 Hz. Los resultados mostraron un incremento en la actividad simpática del grupo hipertenso, lo cual no ocurrió en el grupo no hipertenso luego de la MO (Δ%=59.84%, ... |
