Conduction System of the Heart
心脏传导系统
The conduction system is responsible for the generation and
propagation of impulses throughout the working myocardium 。
传导系统负责在整个工作心肌中产生并传导电冲动。
其中某些结构对心脏功能至关重要,
Certain parts are essential for heart function
Especially the heart's pacemakers (SA node, AV node)
This is why they have duplicate blood supply
尤其是心脏的起搏点(窦房结、房室结)。
这也是它们拥有双重血液供应的原因。
The conduction system includes:
传导系统包括:
① Sinoatrial (SA) Node 窦房结
②Bachmann's Bundle 巴氏束
③④⑤Internodal Pathways 节间束
③Anterior Internodal Pathway (James' Tract) 前结间束(James束)
④Middle Internodal Pathway (Wenckebach's Tract) 中节间束(文氏束)
⑤Posterior Internodal Pathway (Thorel's Tract) 后节间束(Thorel束)
⑥⑦Atrioventricular (AV) Junction 房室交界区(房室结区)
⑥Atrioventricular (AV) Node 房室结
⑦Bundle of His His束
⑧Right Bundle Branch 右束支
⑨Left Bundle Branch 左束支
⑩Left Posterior Fascicle 左后分支
⑪Left Anterior Fascicle 左前分支
⑫Purkinje Fibers 浦肯野纤维
