Chapter 267 Promotion (Part [-])
Lu Chen's compulsory questions have been completed.

His ranking came to No.16!
Among all the contestants, the correct rate of the required questions is quite high.

Especially for those who are currently ranked in the top [-], almost no one makes mistakes in the required questions, but there is a difference in the speed of doing the questions.

The Department of Cardiology is originally a department where academic bullies haunt and gather.

It is very difficult to stump everyone on the regular questions without continuing to increase the difficulty of the questions!

Now, the key to winning or losing is the remaining optional questions!

Among the ten optional questions, choose four.

The scores of these ten questions are not the same.

Some of the questions are worth [-] points, while others are only worth [-] points!

Lu Chen guessed that the scores of the questions are most likely divided by the difficulty of the questions.

……

Lu Chen took a rough look at all ten questions.

Soon, his heart sank to the bottom.

These ten questions are mainly composed of three types of ECGs: difficult ECG, pacing ECG, and esophageal pacing.

At first glance, Lu Chen could feel the difficulty of each question.

Even, there are two pictures in it, which Lu Chen has never seen before!

"It seems that for the time being, we can only choose the four most confident questions!"

Lu Chen thought for a while, and quickly chose the four questions he was most confident about.

The few optional questions he chose were of medium difficulty, and the scores were all around [-].

He is very confident that he can get the scores for these four questions!
……

first question.

After VVI pacing in patients with atrial fibrillation, please make a comprehensive judgment to determine whether the pacing and sensing functions of the pacemaker are normal?
This is another pacing ECG.

Lu Chen thought for a moment, and immediately gave the answer.

"Pacing dysfunction, sensory function is normal."

Second question.

The patient, male, 34 years old, went to the doctor because of freezing all over the body, what was the electrocardiogram diagnosis?

This electrocardiogram is very interesting, the patient is frostbite.

The medical history is a bit complicated, but the electrocardiogram is not difficult.

"Sinus bradycardia, left axis deviation, hypothermic J wave!"

The progress of answering questions is relatively smooth.

Just as Lu Chen was about to do the third question, he suddenly hesitated as if he had thought of something.

If you continue to choose this kind of medium-difficulty topic, although the correct rate can be guaranteed, the score is low!

Even if you do it right, the score for answering two questions correctly may not be as good as someone else's one question!

Lu Chen knew that he was currently not doing the questions fast.

When everyone's level is similar, I don't have much advantage.

Although Lu Chen didn't know his own ranking, but according to the difficulty of the current questions, he felt that he might be outside the top ten.

No idea!

If it was just to interpret the difficult ECG, then Lu Chen would definitely be in the top ten.

But the electrocardiogram in the exam still involves a lot of knowledge about electrophysiology.

The electrocardiogram skill card is just a primary card, and it is extremely difficult for Lu Chen to rank so high.

There are two roads before Lu Chen.

In other words, there are two paths for all contestants.

Conservatives, choose a topic with a low score to ensure that you can get a score.

Radicals choose high-scoring questions, which are difficult, but the correct rate is not high.

For a while, Lu Chen hesitated.

……

At this time, the office of the director of the eighth district in the heart.

Li Yao stared closely at the internship rankings on the test platform.

Lu Chen's ranking is No.14!

However, there are only two questions left to be completed!

"Hey, Lu Chen tried his best, but it's a pity..."

Li Yao shook her head slightly, then sighed.

For the last two questions, as long as there are no mistakes in the top ten, it will be very difficult for Lu Chen to enter the top ten.

"After all, it is still too young, and the knowledge system is too weak."

Jinghua Electrophysiology WeChat communication group.

In the group message, only the people who sent the text live broadcast were left.

Others seldom spoke, and everyone held their breath.

The situation is severe now, and even Professor Lu is ranked outside the top ten.

Not to mention Fan Zhiping, although his ranking has improved, he is still No.40!

Everyone is always watching Lu Chen's ranking changes.

A promotion and a promotion all tugged at everyone's heartstrings.

But with the passage of time, the exam is coming to an end.

The hope of a comeback is getting slimmer!

……

Jinghua Second Hospital, dormitory of Guipei Building.

Lu Chen was silent for a few minutes, and finally decided to choose a difficult topic!

There are a lot of good people in this competition. It seems wishful thinking to break into the top ten with four medium-difficulty questions.

Lu Chen gave up the two questions he chose before, and chose two questions worth 15 points instead!

Optional questions, the third question.

The patient is a 65-year-old female patient with sick sinus syndrome. After implantation of a dual-chamber pacemaker, the picture below shows a non-continuous record of dynamic electrocardiogram. What is the diagnosis?
In front of Lu Chen was a non-continuous record of a dynamic electrocardiogram.

On the electrocardiogram, obvious pacing signals can be seen.

At first glance, Lu Chen thought it must be an abnormal ECG.

However, Lu Chen couldn't tell where the problem was.

There are still 15 minutes until the end of the exam time.

Lu Chen has plenty of time.

He settled down and calmed himself down.

……

In the second area of ​​the heart, the doctor's office.

Gu Xinyue sat in front of the computer.

Judging by his appearance, although he was typing on the keyboard and revising the medical record, his eyes were always fixed on the mobile phone on the table.

On the screen of the mobile phone was the real-time ranking of the electrocardiogram competition.

At this time, there were only 10 minutes left before the end of the exam, and Lu Chen's ranking was No. 14.

"Junior Brother Gu, bed 6 just said that his chest is not feeling well, you should go and have a look."

The voice of my brother came from beside my ear.

Gu Xinyue was stunned for a moment, and when the senior brother repeated it for the second time, she realized that she quickly picked up the phone and said, "Okay, I'll go now."

Gu Xinyue walked briskly. After treating the patient, he immediately returned to the doctor's office.

The ranking of the electrocardiogram contest was opened again.

Only 5 minutes left until the end of the game!
At this time, Lu Chen's ranking has risen again, reaching No.12.

Gu Xinyue stared at the phone screen tightly, not daring to breathe.

"Lu Chen, can you do it?"

For Gu Xinyue, Lu Chen is not only his opponent, but also his friend.

Recalling the scene of the National Skills Competition, Gu Xinyue faintly felt a little expectation.

"Perhaps, Lu Chen can do some impossible things."

……

The moment when the exam time cleared.

The real-time ranking of the test platform will no longer change.

Lu Chen's test paper was also officially submitted, so he couldn't continue to answer the questions.

For the last two questions, Lu Chen exhausted the knowledge of electrophysiology he had learned recently, and wrote down the diagnosis of these two questions.

Exit the test interface and come to the test ranking platform.

When he saw the ranking, Lu Chen breathed a sigh of relief.

His choice was not wrong, he made the right bet!

"Lu Chen, the final score of the second round of exams, No.9!"
