Impulse is conducted unusually much if behavioral potential amplitude is reduced with ascendant rate, change by function of film of cardiac muscle cell, should stimulate a gender to drop, the joint between the cell decreases, impulse of as a result is conducted decelerate or block sluggish
沖動傳導異常多由心肌細胞膜性能改變如動作電位振幅和上升速率降低，應激性下降，細胞間接合減少，以致沖動傳導減慢或阻滯。 -
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。 -
Fold return formation postulate to be : heart somewhere or much place are one - way block sluggish ; impulse is conducted in another way slow ; defer of cardiac muscle of yuanduan of place of block sluggish is excited ; place of block sluggish carries cardiac muscle nearly again excited
折返形成的基本條件為：心臟某處或多處單向阻滯；沖動在另一途徑傳導緩慢；阻滯部位遠端心肌延遲激動；阻滯部位近端心肌再激動。
