Chapter 176

However, the family member still didn't believe it.

Because she couldn't understand either.

Just looking at Zhang Yi's age, he doesn't look like an experienced doctor.

"Hmph! What kind of surgery for a non-beating heart? I don't understand! Anyway, I'm telling you! If anything happens to my mother, I will definitely settle the score with you!"

The family members pointed at the noses of Zhang Yi and Wang Xiaomian while talking.

"Don't think that I am afraid of you because I came all the way to the mainland and have no friends! As long as something happens to my mother, you will definitely have nothing to do with it!"

Faced with the accusations from his family members, Wang Xiaomian was helpless and could only continue to say patiently:

"Please wait a moment. We will have a meeting to discuss it first. We will notify you immediately when there is a result."

At this time, several other family members nearby also advised:

"That's right, Aling, don't be so grumpy. Wait for the doctor to check the situation."

Several people around her tried to persuade her, and then the family member named A Ling returned to the bedside.

But she still didn't have a good look at these doctors.

In fact, the doctor felt a little unhappy, but he could only continue to think of ways to treat the old lady.

Who makes them doctors?

In the office.

Zhang Yi looked at the checklist in his hand over and over again.

I have been thinking about the cause of this disease and how to treat it.

I kept recalling the information in the medical books or papers I usually read.

This was the first time Zhang Yi had seen this situation.

After thinking for a long time, he decided to figure out how to solve it on his own.

But if I continue to think about it, I’m afraid the patient will lose it.

So I still asked the system.

"System? Can you give me some advice?"

[Hint, Bernoulli’s equation! 】

Zhang Yi:......

Can you not give me some powerful hints? !

Your hint is too cryptic!

You have a heart disease and you ask me the equation...

wrong!

Zhang Yi suddenly became serious!

Bernoulli's equation?

Bernoulli's equation? !

"Oh shit!"

"That's right! The most famous corollary of Bernoulli's equation is that when flowing at constant heights, the greater the flow velocity, the smaller the pressure! Yes, yes! That's it!"

Zhang Yi knows!

Although that thing is a very, very, very rare type of heart disease.

It was even discovered in the 1980s and 1990s.

But so far, there are already cases for reference.

Zhang Yi placed a checklist in front of Wang Xiaomian and asked:

"Director Wang, I think I have roughly inferred the reason."

In the office, all the doctors raised their heads!

They all looked at Zhang Yi in surprise!

What?

How long has it been since you read the inspection report?

Do you have results? !

In the corner, Lu Gao glanced at Zhang Yi while holding his tongue.

snort!

He doesn't believe it!

I saw Zhang Yi pointing to the color ultrasound sheet and saying:

“First of all, you see, the examination shows that the ventricular wall of the heart is thickened, but there is no stenosis in several main blood vessels, but then you look at the back, and it says that the compliance is reduced.

Reduced compliance means that the pressure difference is unbalanced, indicating that the flow rate of cardiac blood flow has become different. "

Chapter 135 The cause of the disease was found! obstructive hypertrophic cardiomyopathy

When Zhang Yi said this, an attending doctor in his thirties behind Wang Xiaomian asked:

"Yes, what's so special about this? Many heart diseases, especially heart failure caused by aortic stenosis, have reduced compliance and pressure differences."

Zhang Yi looked at him again and asked:

"Yes, but the color ultrasound shows that there is no stenosis in the main blood vessels. What does this mean?"

Depend on!

Zhang Yi actually asked questions!

Just ask!

The main reason is that they can’t answer this question! !

After Wang Xiaomian looked around, everyone was more confused than him.

Then he could only blink his eyes awkwardly and said:

"This...this means...that we should do another color Doppler ultrasound?"

Well, his dignified director still couldn’t answer.

Zhang Yi shook his head.

He pointed at the ultrasound scan and said:

"It means that the decrease in compliance has nothing to do with the stenosis of the arterial valve, or it has little to do with it. Therefore, even if this patient is sent to the operating table for surgery, it will be useless.

Because even on the operating table, I couldn’t find any narrow areas that needed repair.

Let’s think about another question: Director Wang, why are the drugs that increase myocardial contractility and blood vessel dilation useless, but the patient’s condition worsens instead? "

Wang Xiaomian still shook his head.

If I knew, I wouldn't come to you, brother!

Outside the office, although Xu Minjun’s family members did not believe Zhang Yi.

But when the doctor was having a meeting, they still secretly listened at the door.

Zhang Yi glanced at the door, waved to his family and said:

"If you want to come in and listen, you can."

When the family member named A Ling heard this, she immediately walked in with her hands on her waist.

She's not afraid!

She wanted to listen carefully to how this young man treated his mother!

Watching the family members sit down, Zhang Yi continued:

“It shows that this drug is not only useless, but will accelerate the worsening of the condition.

Then you need to think carefully about the circumstances under which increasing myocardial contraction will make the patient's heart worse!

Here I want to tell you about an equation called Bernoulli's equation.

That is, the mechanical energy of the fluid is conserved, kinetic energy + gravitational potential energy + pressure potential energy = constant.

The most famous inference is that when the flow is at equal height, the flow rate is large and the pressure is small.

So for the patient Xu Minjun, my diagnosis is: obstructive hypertrophic cardiomyopathy, but her obstruction is not the ordinary obstruction of fixed aortic stenosis!

But it is dynamic obstruction! "

Wang Xiaomian: "? ? ? Dynamic... dynamic obstructive heart disease? ! "

"That's right!"

Zhang Yi nodded.
