■位置变化会影响针刺引起的心率(HR)降低,这是由躯体自主神经反射引起的。然而,位置对血液动力学系统的影响-包括HR,血压(BP),针灸期间的心输出量(CO)尚不清楚。本研究全面比较了针刺在仰卧和坐位引起的心血管变化。
■对30名健康男性志愿者进行了全面测量,包括HR,每搏输出量(SV),BP,仰卧姿势15分钟.在左侧LI-10点进行1分钟的手动针刺刺激。至少1周后,所有受试者均以坐姿进行相同的方案.
■针刺前,HR和BP都有增加,坐姿中的SV和CO减少,与仰卧位相比。当受试者处于坐姿时,针刺刺激引起的HR降低更多,与仰卧位相比。针刺诱导的SV增加和舒张压降低在两个位置都没有差异。在坐姿,针刺期间CO减少,与针刺前相比;这没有发生在仰卧位。
■在健康的年轻男性中,针刺对血液动力学系统的影响在仰卧位和坐位之间发生了变化。自主神经张力通过生理反应影响针刺引起的心血管变化,包括躯体自主神经反射和压力反射.
UNASSIGNED: Position change influences acupuncture-induced heart rate (HR) reduction, which is caused by a somatoautonomic reflex. However, the influences of position on the hemodynamic system-including HR, blood pressure (BP), and cardiac output (CO) during acupuncture-remains unclear. This study comprehensively compared cardiovascular changes induced by acupuncture in human beings supine and sitting positions.
UNASSIGNED: Comprehensive measurements were made of 30 healthy male volunteers, including HR, stroke volume (SV), and BP, in a supine posture for 15 minutes. Manual acupuncture stimulation was performed at the left LI-10 point for 1 minute. After at least 1 week, the same protocol was performed with all subjects in a sitting position.
UNASSIGNED: Preacupuncture, there were increases in HR and BP, and decreases in SV and CO in the sitting position, compared with the supine position. Acupuncture stimulation induced HR reduction more when the subjects were in the sitting position, compared with them in the supine position. Acupuncture-induced increase in SV and decrease in diastolic BP were not different in either position. In the sitting position, CO decreased during acupuncture, compared with preacupuncture; this did not occur in the supine position.
UNASSIGNED: The effects of acupuncture on the hemodynamic system changed between the supine and sitting positions in healthy young men. Autonomic nervous-tone influences acupuncture-induced cardiovascular changes through physiologic responses, including the somatoautonomic reflex and the baroreflex.
