Li Qifeng looked at Zhou Yewu staring at him, feeling a little uncomfortable, but he didn't say anything.

He looked at the old lady, as if he wanted to ask about his medical history!

Li Qifeng said: "What's the situation with the old man? Why did he suddenly faint?"

The old lady had red eyes: "My old man shouted that his chest and stomach hurt two hours ago. After taking a quick-acting heart-saving pill, he was not healed. As a result, after more than an hour, he started to feel uncomfortable all of a sudden. I thought he was just uncomfortable for a while, but I didn't think about taking him to the hospital. As a result, I came back from the toilet and found that he suddenly fainted on the ground!"

Quick-acting heart-saving pill? Zhou Yewu suddenly became nervous when he heard that a patient with heart failure had taken this medicine 2 hours ago.

Quick-acting heart pills can increase coronary blood flow and relieve angina pectoris. They are used for coronary heart disease and angina pectoris. Is this patient heart failure caused by myocardial infarction?

Zhou Yewu ignored Li Qifeng and interrupted and asked, "Did grandpa say that his chest is stuffy and feels like he is being pressed by something?"

The old lady nodded desperately, "Yes, he said that he had chest tightness and chest pain! Just like what you said, I felt like something was pressing down on my chest, and I was blocked and I couldn't get up!"

Zhou Yewu thought something, and Li Junfeng started to tease, "Oh, are you studying medicine too?"

Thinking of the attending physician Li Junfeng in the emergency room standing in front of him, Zhou Yewu suddenly felt like he was showing off his skills and hurriedly said, "I'm in the hospital for training."

Li Junfeng didn't ask what department Zhou Yewu was from. Hearing that he was trained, he immediately continued to deal with the patient with heart failure after saying "Oh".

He had just heard the conversation between Zhou Yewu and the old lady, but actually had some thoughts in his mind.

"Go and pull him an ECG of the 18th lead." Li Junfeng shouted to the nurse's desk.

The eleventh-lead electrocardiogram and the twelve-lead electrocardiogram are different!

Li Junfeng took advantage of the nurse's electrocardiogram and chatted with Zhou Yewu again, "Young man, what are you doing?"

Zhou Yewu looked at Li Junfeng who was a little unreasonable and smiled and said, "Guiyi, I haven't arrived for a month."

In addition to being the attending physician of the emergency department, Li Junfeng also has another identity, the teaching secretary of the emergency department!

When he saw Zhou Yewu claiming to be the first year of training, he couldn't help but want to start his teaching model again!

"Do you know the difference between these twelve leads and eighteen leads?" Li Junfeng asked.

I don’t know how many students who come to the emergency internship and regular training have stumped this problem.

Li Junfeng looked at Zhou Yewu's stupid look and completely thought he couldn't answer!

Because good-looking people generally have poor grades, people as good-looking as the boy in front of them should not have good grades! With this idea in mind, Li Junfeng felt expectant to wait and see Zhou Yewu joke after asking!

But what he never expected was that doctor Zhou from the respiratory department was standing in front of him!

Zhou Yewu smiled, thinking that he would be embarrassed to ask such a question?

He licked his tongue with a dry tongue and said, "The regular 12 leads can only cover the myocardium of the anterior inferior wall, and the coverage of other parts of the heart is not comprehensive enough. I suspect that myocardial infarction of the posterior wall needs to be added with three leads of the posterior wall. Patients with right ventricular disease need to add three leads of the right heart. So eighteen leads were generated!"

Zhou Yewu directly answered Li Junfeng's question with the meaning of the 18th lead, and this answer was simple and clear.

The talk was pretty good, and Li Junfeng continued to ask after hearing this: "Then do you know how to put the Eighteen Leaders?"

"Right chest lead, v3r sticks to the right v3 position, v4r sticks to the right v4 position, v5r sticks to the right v5 position, as for the posterior wall lead v7 sticks to the left posterior axillary line, the fifth intercostal intercostal is parallel to v6, v8 sticks to the left shoulder line, the fifth intercostal intercostal is parallel to v6, v7 sticks to the left shoulder line, the fifth intercostal intercostal is parallel to v6, v7

, v9 is attached to the left side of the spine and spreads his fingers parallel to the fifth intercostal v7 and v8." Zhou Yewu explained the position of the eighteen exercise in one breath.

Li Junfeng was dumbfounded and looked at Zhou Yewu in a daze.

She looks so handsome! She is so good at this foundation? It's not in line with common sense!

Li Junfeng always thought that only people who are big and thick like him would spend more time studying and have a solid foundation!

"Brother Feng, the electrocardiogram is out." A nurse ran towards Li Junfeng with the electrocardiogram paper.

Li Junfeng took the electrocardiogram, but he didn't see it himself, so he handed the electrocardiogram to Zhou Yewu.

"I see?" Zhou Yewu took the electrocardiogram with some hesitation.

He has long since returned the level of ECG to the teacher, and he is watching a ball! And he has never understood this complicated ECG at all, whether it is studying or internship! The ECG is a heavenly book for him. It is simply a torture for a mortal to read the heavenly book...

Li Junfeng grinned, smiling like a hooligan: "Many heart diseases require electrocardiograms. Take a look quickly. If you don't understand, I won't laugh at you!"

Zhou Yewu took the electrocardiogram, but he just couldn't understand it without any surprise.

Li Junfeng was still looking at Zhou Yewu with a smile, as if waiting for him to give the answer.

I can't understand the electrocardiogram, but Zhou Yewu heard the old lady say that the old man had chest tightness and palpitations 2 hours ago, and chest pain, but chest pain is not a pressing pain, so it doesn't look like a myocardial infarction, so he guessed an answer casually, "Mynaecology ischemia."

Li Junfeng took the electrocardiogram back into his hand, took a closer look, and then laughed unconcealedly: "What about your sister ischemia in myocardial ischemia? Are you confused?"

This is the moment he is waiting for!

He can't let Zhou Yewu show off in front of him! Then wouldn't he be a teacher secretary be embarrassed?

Li Junfeng began to pretend to be serious and said: "Go back and take a look at a few more electrocardiograms. The identification of electrocardiogram is very important for regular training. You will also get this thing after the standard training exam. You can't do it if you don't have solid basic skills. One question will be 5 points. Moreover, electrocardiogram is something that often comes in handy when rescue is rescued. As a doctor, you must know how to see it!"

I was preached by Li Junfeng, which was something Zhou Yewu had unexpectedly...

Does this stupid and mean leader have this kind of teaching style?

Just when Zhou Yewu was educated a little embarrassed and didn't know how to end it.

Li Junfeng said directly to Zhou Yewu: "There is no good electrocardiogram and you have to study hard in the future. Since you have met me today, let you learn it again."
