ObjectiveThis study aimed to analyze the effect of acupuncture in Heart auricular point on cardiovascular function in healthy subjects. DesignA kinetics cross-sectional experimental study was conducted at Clínica de Acupuntura, Unidad Iztapalapa, Universidad Autónoma Metropolitana, Ciudad de México, México. ParticipantsEight healthy university students (four women) aged 21.12 ± 1.81 (mean ± SD) participated in the present study to investigate the kinetics of the acute effect of acupuncture stimulation at auricular point Heart. InterventionsThe study consisted of one session of manual auricular acupuncture in the Heart point in the right ear. The following data for every heartbeat: Cardiac output (CO), heart rate (HR), stroke volume (SV), mean arterial pressure (MAP), and systemic vascular resistance (SVR) were computed. Manual acupuncture was applied at the auricular point Heart. ResultsThis treatment showed an inhibitory effect on CO, HR, SV, and MAP; and stimulatory effect on SVR. Our results showed that acupuncture at the auricular point Heart initially produced a decrease in both HR and SV, therefore in CO; and secondly, a rise of SVR as a compensatory response. ConclusionsData suggest the possibility of vagal stimulation immediately after auricular acupuncture in Heart point with a secondary sympathetic response.
