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

现在，在情况下，QRS波群都会提前出现，意味着一次提前心室缩。

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异位起搏点，在单一心律带上产生了不同形式QRS波群。

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

就是所谓P波“被阻滞”或QRS波群“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.

心室缩以QRS复合波群形式展现，心室复极以及因此发生舒张波形，则视为T波。

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

因此，QRS波群在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波群代表心室从室间隔开始去极化。

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

在ECG上，心房颤征是没有P波和不规则窄QRS波群。

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

一个QRS波群前房扑波数目，相当于一次心室缩对应心房缩数目。

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

方法观察I导联和aVF导联QRS波群。

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6个胸导联，V1-V6是怎样来记录被称为“QRS波群”除极波形。

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.

在情况下，除极波向下传导到左束支，然后异常地穿过心室，导致一个异常增宽QRS波群。

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、征性“兔耳”QRS波群，个R波。

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

在ECG上，V-tach征是宽而异常QRS波群。

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

QRS波，有时被称为QRS波群，代表电脉冲通过心室传播，或心室去极化。

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

个导联QRS波群均为负值，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波到QRS复合波群时间。

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

大多数情况下，成功传导QRS波群可能较正常宽。

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波群有固定数目P波。

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QRS波群为正，则轴指向与导联大致相同方向。

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，因此，每个周期P波和QRS波群数量之间有一个固定比率。
