Now in a normal electrical conduction system, the AV node is the only place where the signal can get through from the atria to the ventricles.

在一个正常的电传导系统中，房室结是心房向心室传导的唯一通路。

These blocks or delays usually happen because of some sort of damage or fibrosis to the electrical conduction system, the pathways that conduct the electrical signal.

心律失常一般由心脏传导系统（即电信号传导的通路）受损或纤维化导致。

That's due to sort of disorganized ion movement within the cardiomyocytes, and it could also be due to a disrupted electrical conduction system within the heart.

这是由于心肌细胞内某种杂乱无章的离子运动引起的，也可能是由于心脏内的电传导系统被破坏了。

Beyond serving to support his young family, his work focused on many different devices involving electrical conduction and mechanics and it has been posited that this impacted on Einstein's own research during his formative years.

除了养活他年轻的家庭之外，他的工作还集中在涉及导电和力学的许多不同设备上，人们认为这对爱因斯坦在成长时期的研究产生了影响。
