potential pacemaker 中文意思是什麼
potential pacemaker
解釋
潛在起搏點-
Our previous studies demonstrated that agmatine not only reduced the amplitude of action potential ( apa ), maximal rate of depolarization ( vmax ), velocity of diastolic ( phase 4 ) depolarization ( vdd ), and rate of pacemaker firing ( rpf ), but also prolonged 90 % duration of action potential ( apd90 ) in a concentration - dependent manner
我們先前的實驗證明，胍了胺可劑量依賴性地抑制兔竇房結起搏細胞的0相最大上升速度（ v _ （ max ） ） ，動作電位幅度（ apa ）和舒張期除極化速度（ vdd ） ，起搏細胞放電頻率（ rpf ） ，而且能延長90動作電位時程（ apd _ （ 90 ） ） 。 -
The cardiac impulse originates in a relatively small group of primary pacemaker cells. typical primary pacemaker cells have the highest intrinsic frequency in firing. following its firing, there is a slow depolarization called pacemaker potential
位於右心房竇房結內的起搏細胞具有最高的固有發放節律，每次發放后即出現一個緩慢的自動去極化過程，心率主要取決于起搏細胞去極化的斜率。
