Most often, the aberrancy is due to a right bundle branch block because that's the one that has a longer refractory period.

最常见的，这个异常冲动是由于右束支阻滞所引起的，因为它有更长的不应期。

Bundle branch block – blockage within left or right bundle branches.

束支传导阻滞-左右束支传导阻滞。

The names " left bundle branch block" and " right bundle branch block" indicate the side that is affected.

“左束支传导阻滞”和“右束支传导阻滞”提示一侧受影响。

In bundle branch blocks, the UN-affected ventricle depolarizes first.

在束支传导阻滞中，未受影响的心室首先去极化。

Some people with bundle branch blocks are born with this condition.

一些束支传导阻滞患者先天就有这种疾病。

In RIGHT bundle branch block the initial septal activation is unchanged.

在右束支传导阻滞中，初始间隔激活未改变。

In LEFT bundle branch block septal depolarization is REVERSED, from right to left, giving a negative wave in V1.

左束支传导阻滞时，室间隔从右向左反向去极化，V1导联呈负波。

If the ectopic focus originates in the left ventricle, the wave will depolarizing the left ventricle first and then the right ventricle, which produces a QRS complex that looks like a right bundle branch block.

如果异位起搏点源于左心室，这个波将会首先除极左心室，然后是右心室，这会产生类似于右束支阻滞的一个QRS波群。

If the ectopic focus originates in the right ventricle, the wave will depolarize the right ventricle first and then the left ventricle, and this produces a QRS complex that looks like a left bundle branch block.

如果异位起搏点源于右心室，这个波将会首先除极右心室，然后是左心室，这会产生类似于左束支阻滞的一个QRS波群。

Left and right bundle branch blocks are diagnosed and differentiated by looking at ECG recordings obtained from the CHEST leads, which register signal movements in a horizontal plane.

通过观察从胸导联获得的心电图记录，可诊断和鉴别左束支传导阻滞和右束支传导阻滞，这些心电图记录了信号在水平面上的运动。
