У міру того як температура змінюється, пульс також змінюється.

У міру того як means something like as, in proportion as, or to the extent that.

In this sentence:

У міру того як температура змінюється, пульс також змінюється.

it means:

As the temperature changes, the pulse also changes.

This is a fairly formal or neutral written expression. In everyday speech, people may sometimes prefer simpler ways to say as or when, depending on the context, but у міру того як is completely correct and natural.

You can think of it as a multi-word connector introducing a gradual relationship:

• one thing changes,
• and another thing changes along with it.

Температура is in the nominative case because it is the subject of змінюється.

So in the clause:

температура змінюється

the meaning is the temperature changes.

Since temperature is the thing doing the changing, Ukrainian uses the nominative:

• температура = the temperature

If it were a direct object, then another case might appear, but here it is the subject.

Because each clause has its own verb:

1. температура змінюється = the temperature changes
2. пульс також змінюється = the pulse also changes

English can sometimes avoid repeating the verb in certain contexts, but Ukrainian normally keeps the full verb in each clause when both ideas are stated clearly.

So the repetition is natural and helps show the parallel structure:

• as temperature changes,
• pulse also changes.

Змінюється comes from змінюватися / змінитися and means changes / is changing.

Here it is:

• 3rd person singular
• present tense
• imperfective
• reflexive (because of -ся)

Why imperfective? Because the sentence describes an ongoing or general process, not a single completed change. It is about change happening over time.

So:

• змінюється = changes, is changing

The -ся ending often appears with verbs that mean a thing changes itself / undergoes change, rather than someone changing something else.

Compare:

• температура змінюється = the temperature changes
• лікар змінює лікування = the doctor changes the treatment

In the second example, змінює is transitive: someone changes something.

Також means also.

It emphasizes that the second process happens too:

• температура змінюється
• пульс також змінюється

So the idea is: As the temperature changes, the pulse also changes.

It is not always strictly necessary for the grammar, but it is very natural here because it highlights the parallel relationship between the two changes.

Without також, the sentence would still be understandable:

• У міру того як температура змінюється, пульс змінюється.

But that sounds a little flatter. Також makes the connection clearer.

Yes, Ukrainian word order is fairly flexible, and також can sometimes move, though some positions sound more natural than others.

The given version:

пульс також змінюється

is very natural.

You may also see:

• також пульс змінюється — possible, but more marked
• пульс змінюється також — possible in some contexts, but less neutral here

For a learner, the safest pattern is:

• subject + також + verb

So:

• пульс також змінюється

is a good model to remember.

Пульс literally means pulse.

In many contexts, especially medical or semi-medical ones, English might naturally say pulse or heart rate, depending on the situation.

So:

• пульс = pulse
• sometimes in translation, depending on context, it may be expressed as heart rate

In this sentence, pulse is the direct match.

Grammatically, пульс is:

• masculine
• singular
• nominative here, because it is the subject of змінюється

Because the sentence has a subordinate clause followed by the main clause.

Structure:

• У міру того як температура змінюється,
• пульс також змінюється.

In Ukrainian, subordinate clauses are normally separated by commas. The first part sets up the condition or proportional relationship, and the second part gives the main statement.

So the comma is standard punctuation here.

Not with exactly the same meaning.

Коли температура змінюється, пульс також змінюється means more like: When the temperature changes, the pulse also changes.

That is understandable, but коли mainly indicates time: when.

By contrast, у міру того як stresses a gradual or proportional relationship:

• the more / as one thing changes,
• the other changes correspondingly.

So if you want the idea of in proportion as or as ... progressively ..., then у міру того як is better.

It most naturally reads as a general fact or general observation.

That is because:

• the verbs are in the present tense,
• the imperfective aspect suggests an ongoing or repeated process,
• the sentence sounds explanatory or scientific.

So it feels like: As temperature changes, pulse also changes.

In other words, it is describing a general relationship, not necessarily one single event happening right this moment.

It is better to learn it as a fixed expression rather than translating each word separately.

The parts are:

• у міру = literally something like in measure / in proportion
• того = that in a grammatical linking role
• як = how / as

But if you try to build the meaning from each word literally, it may feel confusing. The whole phrase functions together as a connector meaning:

• as
• in proportion as
• to the extent that

So for learning purposes, treat у міру того як as one unit.

Yes: the sentence uses a very typical and clear Ukrainian structure:

• connector + subordinate clause
• comma
• main clause

So:

У міру того як температура змінюється, пульс також змінюється.

This is a nice example of Ukrainian putting the contextual or dependent information first.

You could sometimes rearrange parts of the sentence, but the given order is natural and easy to understand. For learners, it is a good standard pattern:

1. introduce the relationship,
2. state the first process,
3. then give the main result or parallel process.
