Next time we'll write the letter 'Q'.

下次我们要学习写字母 Q。

Queue, very simple, just like the letter " q" , and there is the alphabet.

队列，很简单，就像字母“q” ，还有字母表。

If the first wave after the p-wave is downwards, or negative, it's called a Q wave - which you can remember by the letter Q having a downward tail.

如果P波之后的第一个波是向下，或者说负相，它就叫做Q波，你可以用字母Q有一个向下的尾巴来记。

Q, if you say the letter q, it sounds like the word, that funny word where people stand in a line waiting for something, maybe in a shop waiting to be served.

Q，如果你说字母 q， 它听起来像这个词，那个有趣的词， 人们排着队等待某事， 也许在商店里等待服务。
