Finally, any downward deflection after the R wave is called the S wave.

最后，R波之后的任何向下的偏转波都叫S波。

If the next deflection is upward, or positive, then it's called the R wave.

如果下一个偏转波向上，或者说正相，那么它就叫做R波。

If, though, the first wave after the p-wave is upwards, instead, or positive, you basically skip the Q and just called it an R wave.

如果P波之后的第一个波向上，或者说正相，你跳过Q波，叫它R波就行。

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波群，两个R波。

As in this example in a lead in which the QRS complex ends with an R wave.

在本例中，QRS波以R波结束。

Lead V1 gives a characteristic M shape with a terminal R wave, while V6 sees a broader S wave.

V1导联呈特征性M形，其末端是R波，而V6导联可见更宽的S波。

Lack of depolarizing flow through the dead segment results in a reduction of R wave activity.

坏死段去极化电流缺失导致R波活性降低。

In addition, there is a gradual increase in amplitude of R wave from V1 to V5.

另外，从V1到V5，R波振幅逐渐增大。

In this case it may be helpful to look at R wave progression.

在这种情况下，观察R波的进展可能会有帮助。

This is known as R wave progression.

这就是所谓的R波进展。

So, when an ectopic focus originates in the left ventricle, and moves towards the right ventricle, the V1 lead shows a large positive complex, with a dominating R wave.

所以，当异位起搏点起源于左心室，并向右心室传导，V1导联出现一个有主导地位R波的大型正相复合波。

R wave is produced by depolarization of the main mass of the ventricles.

R波是由心室的主要部分去极化产生的。

Non-progression or poor progression of R wave - R wave stays low and S wave remains deep throughout all chest leads.

R波无进展或进展不良-所有胸导联R波持续较低，S波仍较深。

For rhythm: measure the intervals between the R waves.

测量R波之间的间隔。

This is the most common finding, or as illustrated here, inversion of T waves in leads with dominant R waves loss of concordance.

这是最常见的发现，或者如图所示，在主导R波失谐的导联中T波的反演。

Reverse progression of R wave - tall R wave in V1, tallest in V1 or V2 - is usually seen in right ventricular hypertrophy.

右心室肥厚时，R波反向发展，V1高R波，V2或V1最高。

Such early Q waves may disappear from the patient's ECG, a normal R wave progression may be restored if vessel patency is reestablished within the appropriate time frame.

患者心电图上，早期Q波可能消失，如果血管在适当的时间内恢复通畅，可以恢复正常的R波进程。

In a given ECG lead, T waves are generally concordant with the QRS complex so that in a lead with a dominant R wave such as v6 the T waves are normally upright.

在给定的心电图导联中，T波通常与QRS波群一致，因此在具有主导R波或v6波的导联中，T波通常是直立的。

It is important to be aware that in a proportion of cases Q waves and loss of R wave activity may develop very early in the course of STEMI.

重要的是要知道，在某些情况下，Q波和 R波活动丧失可能在STEMI过程早期发生。
