Chapter 41 The Battle of the Electrocardiogram (Part [-])
"Grandmother, although Daddy's condition is improving now, we still recommend transferring him to CCU. Only in CCU can he get the best treatment!" Sun Guoguo persuaded earnestly.

The old woman stood up slowly and shook her head vigorously.

"Dr. Sun, thank you for your rescue just now, but if we don't transfer to another department or go to CCU, we really have no money!"

Seeing the old woman's resolute attitude, Sun Guoguo sighed, there was nothing he could do about her.

Dong Hao took out two informed consent forms.

One is the informed consent form for refusal to transfer to CCU.

The other is a critical illness notice.

"Mother-in-law, then sign it."

The old lady nodded, and took the pen handed over by Dong Hao.

He crookedly signed his name on the two informed consent forms.

"Thank you, Dr. Sun, and thank you, Dr. Lu."

She said this to Lu Chen.

The two consecutive rescues also allowed the old lady to know Lu Chen, a young doctor who just entered the department.

……

Every time the rescue is over, the first task is to make up the rescue doctor's order and write the rescue record.

"Junior Brother Lu, go and make up the rescue records."

Sun Guoguo led everyone out of the ward.

"Junior Sister Ke, go and make up the emergency medical order, and the others will continue the ward rounds together."

The time for ward rounds is tight, and everyone can only act separately to improve efficiency.

After receiving the order, Lu Chen and Ke Yue returned to the doctor's duty room.

……

In the doctor's office at this time.

Most of the medical teams are making ward rounds, and only a very small number of doctors are making supplementary medical orders.

"Lu Chen, you are really amazing."

Ke Yue whispered.

"I heard Senior Brother Dong say that you sucked out the blood clot just now."

Lu Chen turned on the computer and smiled, "If you have used the suction tube once, you will know that this thing is actually very simple, without much technical content."

"Oh." Ke Yue pursed her lips. Although Lu Chen said so, she knew that Lu Chen was being humble.In the two months since she came to the department, she hasn't seen any other students using a sputum suction device.

Lu Chen started to write down the emergency records, and Ke Yue filled out the doctor's orders.

The time of the doctor's prescription and the time of the course of medication should correspond, and the two communicated while completing their respective tasks.

Because of the experience of writing rescue records in the morning, Lu Chen is more comfortable writing rescue records now.

About 10 minutes later.

Both Lu Chen and Ke Yue have completed their respective tasks and are ready to return to the large team of ward rounds.

At this time, another medical team in the eighth district of the heart, with about seven or eight doctors, suddenly returned to the doctor's office.

The leader was a female doctor in her 40s, followed by other doctors in the group.

"In fact, the electrocardiogram is very simple. You have to read and interpret it more clinically. Different electrocardiograms may have different meanings when they appear on different people."

The female doctor walked into the office and turned her head to educate the students behind her from time to time.

Lu Chen recognized her.

She is the senior chief physician of another medical group in the eighth district of the heart, and also the deputy director of the ward of the eighth district of the heart—Lin Cui.

"Hey, don't leave, you two students."

Lin Cui suddenly pointed at Lu Chen and Ke Yue.

Lu Chen and Ke Yue, who were about to leave, paused and looked at Lin Cui suspiciously.

"I'll recognize a few electrocardiograms for you later, and all your students have to come and study." Lin Cui sat at the desk in the center of the office, and said earnestly, "You must grasp the opportunity to read the electrocardiogram when you usually have it. .Otherwise, when it comes to clinical practice, looking at the electrocardiogram is like reading a bible. When the time comes to find a quick guide to electrocardiogram, it will be heresy."

Interpretation of ECG?
Lu Chen was not afraid of interpreting the ECG, but why did Lin Cui keep them?
Ke Yue on the side behaved a little abnormally, she hesitated to come forward.

"What's wrong?" Lu Chen asked in a low voice.

"I, I'm not very good at recognizing electrocardiograms." Ke Yue said timidly, "If Director Lin asks, what should I do if I don't know anything?"

"It's because you don't know how to learn." Lu Chen smiled, "If you know everything, what are you going to do?"

Director Lin had spoken, so Lu Chen could only walk towards their small group.

Ke Yue gritted her teeth and followed slowly.

……

in the ward.

"Why haven't they come back yet?"

Sun Guoguo has found bed No. 6, but Lu Chen and Ke Yue are still missing.

"Xiao Dong, go to the office to see if Junior Brother Lu and the others have encountered some trouble, why haven't they come back yet?"

"Okay, senior sister." Dong Hao nodded, holding a stack of medical records, and walked towards the doctor's office.

……

"First of all, when we learn something, we must know what its principle is! And what is the principle of electrocardiogram? Does anyone know?"

Lin Cui sat on the desk in the center of the office, surrounded by a group of people, most of whom were graduate students, trainees and interns.

"Xiao He, explain it to everyone."

Lin Cui smiled and looked at a girl beside her.

This girl is called He Sirong, and she is a graduate student this year. She has a very high score in the preliminary examination, ranking third in the whole Department of Cardiology.

He Sirong smiled and nodded, looking confident.

"The principle of the electrocardiogram refers to the response of the action potential of atrial myocytes and ventricular myocytes on the body surface, but the electrocardiogram is not the response of a single cell's action potential, but the depolarization and repolarization of most atrial myocytes and ventricular myocytes. Comprehensive response."

"Because the depolarization or repolarization process of the whole atrial muscle and ventricular myocytes is completed instantaneously, the electrocardiogram on the body surface has a corresponding relationship with the action potential map of the cardiomyocytes."

"Well, classmate Xiao He made it very clear."

Lin Cui showed a gratified smile, then picked up a piece of waste paper and started her teaching part.

On the back of the waste paper, Lin Cui drew a simple electrocardiogram, including P, QRS, T waves and so on.

"Then let me take the ventricular muscle as an example. Phase 0 and its process of spreading in the ventricle are equivalent to the R wave of the electrocardiogram."

"Phase 1 is equivalent to the J point or J wave of the ECG, phase 2 is equivalent to the ST segment of the ECG, phase 3 is equivalent to the T wave of the ECG, phase 4 is equivalent to the baseline of the ECG, and the action potential duration of the whole heart is equivalent to the ECG QT interval."

……

Lu Chen, Ke Yue and everyone stood around Lin Cui, listening carefully to her temporary lecture.

At some point, Dong Hao also came.

"Damn, if I knew it was Mr. Lin giving the lecture, I wouldn't go back to the office even if I said nothing!" Dong Hao walked to Lu Chen's side and said helplessly, "Whenever she gives a lecture, everyone has to listen to the lecture with peace of mind, and you are not allowed to leave .Otherwise, she's going to start freaking out."

He was going to tell Lu Chen and Ke Yue to go back and continue to follow the ward rounds.

Now it's good, he has put himself in it.

"It's not enough just to have rich theoretical knowledge." Lin Cui smiled, and then ordered the doctor at the side to bring some electrocardiograms, "These five electrocardiograms are all the electrocardiograms of the patients currently in the department. Let's take a look together."

Lin Cui also noticed the three of Lu Chen.

"Are you the students of the director's group?"

Lu Chen nodded, "Yes."

"That's great, let's take a look at these electrocardiograms."

"Ok."

Lu Chen stepped forward, while Ke Yue's face was slightly pale, and he followed behind Lu Chen slowly.
