On the computer assessment interface, there is a graphic question about medical three-dimensional space.

"This, this is the electrocardiogram vector?!"

Lu Chen frowned and stared at the topic in front of him.

He originally thought he would be tested on the interpretation of electrocardiograms, but he did not expect to be tested directly on the vectors of electrocardiograms!

Vector is a quantity used in physics to express both magnitude and direction. It is called a vector.

The heart is a three-dimensional organ. The instantaneous comprehensive ECG vectors generated by electrical stimulation move in all directions in space. The force of each instantaneous comprehensive vector is represented by a point. The distance between each point and the origin represents the magnitude of the vector force.

ECG vector is the most basic knowledge of electrophysiology, and it is also the most complex knowledge.

If there is no master to guide you, and you rely solely on personal self-study, it will be difficult to even get started with ECG vectors!

However, once the ECG vector can be understood, no matter how complicated the ECG is, it can be analyzed from the fundamentals to obtain an accurate diagnosis.

"This...I don't know how..."

Lu Chen looked at the topic of ECG vector and scratched his head with a helpless expression.

When it comes to interpreting electrocardiograms, he still has some experience.

But when it comes to the knowledge of ECG vectors, he is also a layman!

…

There are a total of 10 questions in the assessment.

Lu Chen was stumped by this first question.

"I can only skip this question."

Because the entire assessment has a time limit, the paper will be handed in automatically when the time is up.

Then Lu Chen clicked the "skip" button.

Question two.

It’s still a question of ECG vectors!

Lu Chen's heart had sunk to the bottom.

If the next question is still about ECG vectors, then he is almost out of luck in this assessment!

Keep "skipping"!

The third question is finally not about the ECG vector, but about the anatomy of the heart!

This is a color three-dimensional anatomy diagram of the heart.

The question requires identifying the ten locations marked on the anatomy diagram.

Most of these anatomical locations are related to electrophysiology and are the origins of various arrhythmias.

The answer time is only two minutes.

Lu Chen quickly browsed through the entire anatomy diagram, and he only identified the names of six anatomical locations.

The other four anatomical positions are rarely used clinically, so Lu Chen could only guess their names based on the relationship between the upper and lower structures.

"call……"

Finished the third question.

Lu Chen took a deep breath to relax his tense nerves a little.

The difficulty of this examination has exceeded the difficulty of any of his previous medical examinations!

It’s really beyond my capabilities!

Then comes the fourth question, which is still an anatomy question!

This time the test was different from the third question, it was about the fine anatomy of the heart conduction system.

Lu Chen had no idea what to do!

He has never seen this kind of anatomy diagram, how can he take the exam?

It seems that we can only continue to "skip"!

But when Lu Chen clicked the "Skip" button, a gray dialog box immediately popped up on the interface.

"Three questions have been skipped and the assessment failed!"

Failed after skipping three questions in a row?

After repeatedly confirming that there was no fault in the assessment system, Lu Chen had a wry smile on his face. He rubbed his sore eyes and sighed slightly.

The assessment failed!

When the assessment began, he was still committed and confident.

He was relatively confident in his electrocardiogram level, but reality gave him a hard lesson.

After trying four questions, I couldn't do three of them, and I could only do half of the one I knew how to do.

The elite group assessment of the Electrophysiological Society is really not easy!

However, Lu Chen thought for a moment and realized that this was after all a gathering place for the best electrophysiological talents in the city.

As a new graduate student, it would be great for him to be able to participate in this kind of assessment.

If you want to pass the elite group assessment, you will probably have to practice for several years.

Thinking of this, Lu Chen looked away.

There are three opportunities for the elite group assessment of the Electrophysiology Society every year, and Lu Chen has already wasted one.

At the same time, this assessment also reminded Lu Chen.

In the field of electrocardiography, if you want to make progress, the study of electrocardiogram vectors must be put on the agenda as soon as possible.

…

At this time, it was in a bedroom downstairs from Lu Chen.

Gu Xinyue is sitting in front of the computer.

On his computer interface, there were clearly test questions for the "Elite Group" of the Society of Electrophysiology!

And he has already completed the fifth question, the electrocardiogram interpretation question!

Suddenly, a gray-white dialog box popped up on the interface.

"The total answering time has reached 20 minutes, and the paper is being handed in automatically..."

When Gu Xinyue saw this dialog box, she shook her head in disappointment.

He has tried his best to speed up the questions and save time, but half of the questions are still unfinished.

Based on past elite group assessment results, at least seven questions need to be answered correctly to pass the elite group assessment.

If all ten questions are answered correctly, the assessment of "core group members" will be triggered.

As for the assessment of core group members, Gu Xinyue didn't dare to think about it.

But for the assessment of the elite group, he felt that if he worked harder, he would still have a chance to pass.

There are three opportunities every year, and there are nine opportunities in the three years of postgraduate study.

Gu Xinyue calculated that after graduating from graduate school, she should be able to pass the core group's assessment.

While studying, if he can become a member of the elite group of the Municipal Electrophysiology Society, it will be of great benefit to him whether he is studying for a Ph.D. or finding a job.

…

The next day.

Heart zone eight, doctor's office.

The test results of 12 patients are out.

The concentration of "Digitalis" in the blood exceeded the standard, and exceeded three times!

"It's really digitalis poisoning!"

This result is actually not surprising to everyone, but how the patient was poisoned is another problem!

doctor's office. UU reading www.uukanshu.net

Sun Guoguo was on the phone with Li Yao, discussing the specific treatment methods for the 12-bed patient.

If it is a clinical overdose, just stop the medication and the patient's symptoms will be relieved immediately.

For this kind of "digitalis" poisoning effect that has no obvious cause, it is still necessary to focus on "detoxification".

"Okay, Teacher Li, then I will use activated carbon to absorb the toxins first."

After hanging up the phone, the expression on Sun Guoguo's face became much more relaxed.

With teacher Li Yao helping to ensure the treatment plan, Sun Guoguo's pressure was much less.

…

Eight zones in the heart.

In the ward.

"Am I really poisoned?"

The female patient in bed 12 looked gloomy and uncertain when she heard Lu Chen's affirmative answer.

"Auntie, this is the test sheet."

Lu Chen printed out a copy of the results from the laboratory.

"The concentration of digitalis in your blood has exceeded the standard, reaching the standard for diagnosing poisoning."

"Can you give me the test results?"

"Well, you can make a copy and remember to return the original."

"good."

…

afternoon.

Eight zones in the heart.

As soon as Lu Chen went to work, the female patient in bed 12 found the office.

"Doctor Lu, this is the original."

The female patient returned the original document to Lu Chen.

"Um."

Lu Chen stuffed the original test report into the medical record.

All examination and laboratory tests of the patient need to be filed in the medical record.

"Doctor Lu, I... have something I want to tell you."

At the door of the ward, the female patient in bed 12 frowned deeply, as if she had something to hide.
