Chapter 341 The 6th Person!

but!

The first question in the preliminary round stumped everyone!

When Lu Chen saw the title, he was stunned.

He has never done this type of problem before.

The pacemaker is one of the most important elements in electrophysiology.

The usual assessments are all related to electrophysiology.

The question is, identify the pacemaker through the following chest X-ray!

The first question is not the interpretation of electrocardiogram, nor is it the identification of electrocardiogram of pacemaker...

Instead, the manufacturers and types of different pacemakers are judged by the pacemaker imaging displayed on the chest X-ray.

In the past, in clinical practice, when many patients could not provide the manufacturer and type of pacemaker, clinicians could identify it through chest X-rays.

This first question is a new approach.

It seems to have nothing to do with electrophysiology, but it is closely related to electrophysiology interventional surgery.

Without several years of experience in the field of electrophysiological intervention, it would have been impossible to determine the model of a pacemaker through chest X-ray imaging.

…

Lu Chen was confused for the first time.

The pacemaker shows an outline under X-ray.

It's just that he usually never pays attention to such details. Which kind of pacemaker will have which kind of characteristic outline? Lu Chen couldn't tell for a while.

Except for Lu Chen, most of the contestants present were stunned.

This first question directly gave everyone a warning.

On the judges' bench.

Ouyang Ming smiled, "Who asked the first question? Who among these young doctors today would pay attention to such details?"

Jia Bo echoed.

"Yeah, I think back when we first learned about electrophysiological intervention, we were familiar with the shape of every pacemaker. But now the information system is more complete, and patients can easily adjust all the previous pacemakers. Medical records, including what kind of pacemaker you are using.”

Ouyang Ming nodded, "Yes, times are advancing, and many clinical techniques have long since disappeared. However, I am curious now, what is the accuracy rate of this question?"

At the judges' table, everyone looked at the ranking list in front of them.

Currently, all eighty contestants have zero scores!

…

Lu Chen looked at the chest X-ray that appeared in the question several times, but he still couldn't tell what type of pacemaker it was.

There are currently many types of pacemakers on the Chinese market, including single-chamber pacemakers, dual-chamber pacemakers, and biventricular pacemakers, and the basic settings and functions of pacemakers from different companies or manufacturers vary.

In addition, the market is dominated by pacemaker manufacturers such as Medtronic, St. Jude, Boston, and Biotronix.

Time passed by minute by minute.

Lu Chen still couldn't make a judgment.

The five-minute time limit for the first question is about to pass.

At this moment, the ranking on the leaderboard finally changed!

No. 8 Yu Weiguang successfully answered the first question, earned two points, and ranked first!

The contestants cannot see the ranking list, but everyone can feel the tense atmosphere.

Lu Chen thought to himself, "Does the first question have to be guessed?"

While hesitating, an idea flashed in Lu Chen's mind. How could he forget about the system's virtual space?

In the system virtual space, there are various types of pacemakers.

Every time before starting virtual training, the system will let Lu Chen choose by himself.

Because Jinghua Second Hospital uses Medtronic instruments, Lu Chen chose Medtronic.

With a thought, Lu Chen immediately entered the virtual space.

With less than half the time, he had to seize the time and quickly write down the characteristics and models of other pacemakers.

…

In the system virtual space, rows of common pacemakers appeared in front of Lu Chen's eyes.

He immediately noticed that each pacemaker had specific letters and patterns on it.

For example, for St. Jude's pacemaker, SJM stands for St. Jude, HM stands for Pacemaker Fortunately, and MRI stands for Magnetic Resonance Compatible.

Boston Scientific Corporation, BSC stands for Boston Scientific Corporation, and 011 represents the product model.

Solin Company, the pacemaker X-ray identification only has the product model number.

Secondly, when the X-ray mark of the pacemaker is unclear, the manufacturer and model can be determined based on the pacemaker's characteristic appearance.

St. Jude's pacemaker looks like a mango.

Boston Scientific's pacemaker looks like sunglasses.

The BIOTRONIC pacemaker looks like a bird's beak...

…

In addition, Lu Chen also noticed another point: the wiring methods of various pacemakers are different!

St. Jude's pacemaker has a unique rectangular circle.

The Boston Scientific pacemaker is partially wired with several wires arranged side by side, like a centipede.

The wiring part of the BIOTRONIX pacemaker is similar to the tableware set on the dining table.

…

Lu Chen quickly summarized these three characteristics and memorized the common differences between the products of the five manufacturers.

Now, there is only the last minute left before the end of the first question!

At this time, in addition to Yu Weiguang, there were four other contestants on the ranking list who successfully solved the first question.

However, their time is longer than that of Yu Weiguang, so Yu Weiguang is still ranked first.

"It seems that only these five contestants can complete the first question."

Jia Bo looked at the rankings and smiled.

In addition to Yu Weiguang, there was another contestant from the Kyoto University School of Medicine who also successfully completed this question.

Ouyang Ming was about to nod, but suddenly found that the ranking in front of him had changed again!

Originally, only five people had scores, and now suddenly another one appeared...

"Is it Lu Chen?!!!"

When he saw the name of the sixth contestant, Ouyang Ming was stunned. It turned out to be him? !

Ouyang Ming never thought that Lu Chen, a young man in his twenties, could also solve such a difficult question!

Jia Bo also saw the name "Lu Chen".

He frowned slightly, feeling that the name seemed familiar, but he couldn't remember it.

...

Outside the venue, many people didn't know Lu Chen's name, so there was not much reaction.

However, those who knew Lu Chen were completely stunned at this moment!

Cheng Guowen was a little bit unbelievable.

The first question, like this biased and weird question, Min Xiaobo and Fang Yi couldn't solve it, but Lu Chen could solve it?

This is not a multiple choice question, but there are no options, so you can't guess. UU Reading www. ｕukaｎshu.net

Under the watchful eyes of the crowd, Lu Chen couldn't cheat.

In other words, he did it entirely on his own ability!

Cheng Guowen took a deep breath.

During this period, he had been guiding Lu Chen's learning in the simulated operating room.

He felt that he knew Lu Chen's background very well.

But today, he suddenly felt that Lu Chen in front of him was a little strange!

...

And on the court.

Lu Chen breathed a sigh of relief.

Within ten seconds before the end of the game, he quickly typed the answer to the first question on his laptop.

The answer to this question was entirely the work of the system.
