Chapter 42 The Battle of Electrocardiogram (Part [-])
Five electrocardiograms were circulated to each other.

Lu Chen is very interested in the electrocardiogram.

During the internship, he taught himself the electrocardiogram for a long time.

However, it is easy to get started with electrocardiogram knowledge, but it is extremely difficult to master it.

Electrocardiogram, a small piece of paper, records the changes of the heart electric vector on the human body surface.

Its magic lies in that through this insignificant image, it can give everyone insight into various heart-related diseases, including arrhythmia, coronary heart disease, myocarditis, pericarditis, etc.

Even a small change corresponds to the occurrence of a certain disease.

A small and careful electrogram contains a big universe!
Lu Chen has learned by himself, thinking that he has only learned the superficial.

Everyone whispered and discussed the diagnosis of the electrocardiogram.

Lu Chen flipped through the five ECGs.

Two of them.

It is the electrocardiogram of the more common arrhythmias in the Department of Cardiology, which are frequent premature ventricular contractions and atrial fibrillation.

There is another electrocardiogram of acute inferior wall myocardial infarction.

As for the other two, Lu Chen didn't see the diagnosis at the first time.

After the circulation time was over, the five ECGs returned to Lin Cui.

She arranged the five ECGs one by one and placed them on the table.

"Okay, then I will start to test everyone."

Lin Cui looked around the crowd and picked out the first ECG.

"Student, please answer first, what is the diagnosis of this electrocardiogram? The reason must also be given."

The one named by Lin Cui was a quiet boy. He was a regular trainee in Lin Cui's group, and this year was his second year of regular training.

"The QRS wave in this electrocardiogram is wide and deformed, which should be premature ventricular contraction. Because there are four premature beat waves with the same shape, it should belong to frequent single-source premature ventricular contraction."

Lin Cui nodded with a smile, and said: "Well, it seems that you have studied hard. This picture is indeed frequent premature ventricular contractions. Then I will ask the next question, which is also about this electrocardiogram."

"Now that you know frequent premature ventricular contractions, let's talk about the origin of premature ventricular contractions in this picture."

As soon as the voice fell, there were whispers around.

Origin of ventricular premature beats?

This relates to the pathological anatomical location of the heart.

However, all the students here are students who have just entered the clinic, and few people pay attention to the anatomical position of the heart.

This question is beyond the outline!
Pearson scratched his head, showing embarrassment.

"Director Lin, I, I won't."

Lin Cui smiled, then turned to look at another intern.

"how about you?"

The intern was startled, and quickly waved his hands, "Director, I can't either."

Everyone was chattering, but no one answered the point.

"Mr. Lin, this should be a premature beat originating from the apex of the heart."

Suddenly, He Sirong on the side spoke slowly.

Lin Cui smiled, put the electrocardiogram in front of He Sirong, and said, "Why?"

"I have recited similar formulas. The main wave of the QRS wave in leads II, III, and aVF is downward, and the main wave in lead aVL and aVR is upward. It is a premature beat originating from the apex." He Sirong smiled.

"Well, not bad." Lin Cui nodded with satisfaction, "The deeper reason is because of the electrocardiogram vector, but you can answer this point, which is already very good."

He Sirong is Lin Cui's graduate student.

She can answer this question, which makes Lin Cui's face bright.

"Okay, let's see the next one then."

As soon as this electrocardiogram was taken out, everyone had smiles of "I know" on their faces.

This is an ECG of acute inferior wall myocardial infarction, typical ST-segment elevation in leads II, III, and aVF.

Lin Cui picked a graduate student who was rotating in the Department of Cardiology.

"Excuse me, which is the root of the culprit blood vessel in this electrocardiogram of acute inferior myocardial infarction?"

What?Criminal blood vessel?
As soon as Lin Cui's question came out, everyone was confused.

She directly gave the diagnosis of acute inferior myocardial infarction, but instead asked about the location of the culprit's blood vessels.

Good guy, you're completely out of line.

Director Lin Cui is really "insidious" and "cunning"!

"This..." The boy scratched his ear and cheek, "The right crown or the circumflex branch?"

Lin Cui smiled lightly, "You little guy, you have mentioned both possibilities, and I just want you to judge which one of the above is it?"

"Director Lin, I don't know..." The boy curled his lips. He is not a graduate student in the Department of Cardiology, so why do he know so much?
"Who knows?"

Lin Cui looked at everyone.

Seeing no one answered, she glanced at He Sirong.

He Sirong understood, cleared his throat, and said: "Mr. Lin, the ST segment elevation in this picture is STⅢ>STⅡ, which should be due to right coronary occlusion."

Everyone looked at Lin Cui's expression and found that she was smiling all over her face.

It seems that He Sirong was right again!
Lu Chen looked at He Sirong. He didn't expect this girl to be quite powerful. Her electrocardiogram level should have surpassed most of the people present.

It is not easy to have this level in the first year of research.

"Okay, then look at the third ECG."

Lin Cui took out the third ECG.

This time, no one dared to comment easily.

Just in case, Lin Cui asked another "wonderful" question...

Lu Chen looked at this electrocardiogram.

Very simple, it is a common electrocardiogram of atrial fibrillation.

In cardiology, the ECG of atrial fibrillation and premature beats should be the most common and easy to identify.

"You answer."

Lin Cui raised her hand and pointed at Ke Yue beside Lu Chen.

Ke Yue was startled, and walked forward slowly.

"What is the diagnosis of this EKG?"

This time, it was a normal question.

But Ke Yue lowered his head, looking at the electrocardiogram helplessly.

I didn't hold back a word for a long time.

half an hour.

The smile on Lin Cui's face has disappeared, replaced by a serious face.

"Can't you see any electrocardiogram?"

Ke Yue's face was flushed, red reaching the ears.

But still didn't say a word.

Lu Chen frowned. He was standing beside Ke Yue. Although he wanted to help, he couldn't remind him so openly.

"I remember, you seem to be Director Li's student?"

Ke Yue nodded silently.

"But you can't even see such a simple electrocardiogram?"

"Look carefully! See if there is a P wave!"

Lin Cui's volume increased a bit, and the office suddenly became silent.

"Can't you see it yet? Tell me, what is this electrocardiogram!"

Just after Lin Cui finished speaking, everyone present glanced at each other, and then said the word "atrial fibrillation" unanimously.

……

In the ward, Sun Guoguo had already checked the room.

Lu Chen and Ke Yue haven't come back yet, and Dong Hao, who was sent out, hasn't come back either!
Sun Guoguo led the crowd back to the doctor's office. When he saw the crowd gathered together and Director Lin was giving a lecture, he suddenly realized.

"Doctor Sun, it's just in time for you to come back."

Sun Guoguo, who had just walked into the doctor's office, was stopped by Lin Cui.

"You have to teach this child well!"

Sun Guoguo looked in the direction Lin Cui was pointing at. It was Ke Yue who was lowering his head.

"This kid can't even recognize the electrocardiogram of atrial fibrillation!"
