用心血管功能程序,将左心室压、动脉压和升主动脉流量3个生理信号经微机运算后获得29个心血管生理参数,证明此程序在心血管功能研究中较为理想。电针家兔内关穴区时,由于刺激参数不同,可引起降压或升压反应,在升压或降压中,副交感神经均处于抑制状态,提示副交感神经系统的抑制状态可能与针刺作用有关。针刺内关穴区时,特别在升压反应中,交感神经处于兴奋状态,可能是机体应激反应的表现。 With cardiovascular function program, the left ventricular pressure, arterial pressure and ascending aorta flow of three physiological signals obtained by microcomputer computing 29 cardiovascular parameters, proves that this procedure is ideal in the study of cardiovascular function. Electroacupuncture rabbits in Neiguan area, due to different stimulation parameters, can cause antihypertensive or antihypertensive response, in the step-up or step-down, the parasympathetic are in inhibition, suggesting that the parasympathetic nervous system inhibition may be related to acupuncture Relevant role. Acupuncture Neiguan area, especially in the step-up response, sympathetic in an excited state, the body may be the performance of stress response.
