Now - in both these situations, the QRS complex comes in early, which means an early ventricular contraction.

现在，在这两种情况下，QRS都会提前出现，意味着一次提前的室缩。

Also, you might have multiple ectopic foci PVCs, producing different appearing QRS complexes on a single rhythm strip.

同样，你可能有许多室性期前缩的异位起搏点，在单一的上产生了不同形式的QRS。

This is known as a " blocked" P wave or a " dropped" QRS complex.

这就是所谓的P“被阻滞”或QRS“脱落”。

The ventricular contraction is seen as a QRS complex, and the ventricular repolarization, and therefore it's relaxation, is seen as a T-wave.

室缩以QRS复合的形式展现，室复极以及因发生舒张的形，则视为T。

Thus, the QRS complex starts as predominantly negative in V1, and ends as predominantly positive in V6.

因，QRS在V1开始时主要为负，在V6时以正性结束。

The QRS complex represents depolarization of the ventricles which starts with the interventricular septum.

QRS代表室从室间隔开始的去极化。

On an ECG, atrial fibrillation is characterized by absence of P-waves and irregular narrow QRS complexes.

在ECG上，房颤动的特征是没有P和不规则的窄QRS。

The number of flutter waves preceding a QRS complex corresponds to number of atrial contractions to one ventricular contraction.

一个QRS前的房扑的数目，相当于一次室缩对应的房缩的数目。

This method looks at the QRS complex in lead 1 and lead aVF.

这种方法观察I导联和aVF导联的QRS。

As an example, consider how the 6 chest leads - V1 through V6 - register this depolarization wave form called the QRS complex.

作为例子，我们来看一下这6个胸导联，V1-V6是怎样来记录被称为“QRS”的除极形的。

In this situation, the depolarization wave conducts down the left bundle branch and then through the ventricles aberrantly, resulting in an abnormally wide QRS complex.

在这种情况下，除极向下传导到左束支，然后异常地穿过室，导致一个异常增宽的QRS。

Lead V6 sees the opposite, producing a wide, characteristic " bunny ears" QRS complex with two R waves.

V6导联则相反，产生一个宽的、特征性的“兔耳”QRS，两个R。

On an ECG V-tach is characterized by wide and bizarre looking QRS complexes.

在ECG上，V-tach的特征是宽而异常的QRS。

The QRS wave, which is sometimes called the QRS complex, represents the spread of the electrical impulse through the ventricles, or ventricular depolarization.

QRS，有时被称为QRS，代表电脉冲通过室的传播，或室去极化。

Negative values of the QRS complex in both leads are indicative of extreme axis deviation.

两个导联的QRS均为负值，表明存在极端轴偏移。

Also, the closer the ectopic focus is to the AV node, the shorter the PR interval, which is the time from the P wave to the QRS complex.

并且，异位起搏点越靠近房室结，PR间期就越短，也就是P到QRS复合的时间。

In majority of cases, the successfully conducted QRS complexes may appear broader than usual.

大多数情况下，成功传导的QRS可能较正常宽。

In some type II blocks, there is a fixed number of P waves per QRS complex.

在某些II型传导阻滞中，每个QRS有固定数目的P。

If the QRS complex is positive in that lead, the axis points to roughly the same direction as the lead.

如果该导联的QRS为正，则轴指向与导联大致相同的方向。

As this usually repeats in regular cycles, there is a fixed ratio between the number of P waves and the number of QRS complexes per cycle.

由于它以规则周期重复，因，每个周期P和QRS数量之间有一个固定的比率。
