行神经瘤周围松解术后，分别刺激神经瘤的近端和远端神经干，记录靶肌肉的 CMAP，测量其波幅，并计算 PDAR。
After neurolysis, the involved nerve was stimulated both proximally and distally to the neuroma, and compound muscle action potential (CMAP) was recorded in the target muscle of the tested nerves. The amplitude of CMAP was measured and the PDAR was calculated.
AIM To investigate the dynamic variations of monophasic action potential duration(MAPD100) and transmural dispersion of repolarization(TDR) in the ischemic zone after coronary artery ligated and to observe the changes of the MAP parameters following blocking the KATP channel.
ConclusionRadix Aconiti Kusnezoffii can block the conduction of action potential of nerve reversibly.
LAs block action potential generation by blocking voltage – gated Na + channels.
III类抗心律失常药物 (例如胺碘酮) 是通过延长动作电位来发挥作用的。
Class III anti-arrhythmic drugs (such as amiodarone) act ia prolongation of the action potential.
By using standard microelectrode technique, we studied the transmembrane action potential on rabbit conus arteriosus (infundibulum).
