Effects of vagal stimulation on monophasic action potentials (MAP) and transmembrane potentials (TMP) of hyperkalemic rabbit heart were investigated. The results showed that ventricular conduction block induced by hyperkalemia can be improved by vagal stimulation. Amplitude of MAP (MAPA) and maximum rate of rise of MAP (MVmax) were increased, durations of MAP(MAPD) lengthened. Also in single ventricular cell amplitude of action potential (APA) and maximum rate of rise of action potential (Vmax) were increased, while durations of action potential (APD) lengthened. In addition, MAPD and APD measured at the same site are completely in accordance.

This paper mainly introduces the design, structure and software of the pulse condition meter. It's suggested that Chinese Traditional Medicine be developed into a preeminent one in the world.
