Effect of sympathetic auricular acupoint in orthostatic response

Objective: To elucidate the effect of auriculopuncture in Sympathetic points on autonomic function, we investigated heart rate (HR) response to orthostatic challenge healthy subjects. Design and setting: An experimental cross-sectional study was conducted at Acupuncture Clinic, Universidad Autónoma Metropolitana, México. Participants. Twenty university students (twelve women) aged 22.7 ± 1.5 (mean SD) participated study. Interventions outcomes: The consisted two sessions auricular acupuncture point right or left ear. data for continuous normal beat-to-beat recording derive statistical parameters R-R intervals electrocardiogram obtained using SphygmoCor equipment (AtCor Medical Pty Ltd, Sidney, Australia). registration periods were computed a supine position then after standing. primary outcomes changes velocities HR increase, bradycardia secondary response, interval between times maximum increase minimum response. Results: ear raises velocity initial decreases elicits shortening period HR, all cases significant. Otherwise, did not produce significant studied. Conclusion: Data suggest that vagal suppression active
