  Lu Chen stood up and faced everyone in the classroom.

   His eyes were firm and he didn't care what other people were saying.

   "Lu Chen, what did you just say?" Zhang Shuqing thought that Lu Chen was wrong and asked again, wanting to give him a chance to correct.

  Lu Chen was not in a hurry, and still insisted on the sentence just now:

   "Is this patient's ECG a bradyarrhythmia or a tachyarrhythmia?"

   Zhang Shuqing's complexion changed.

   He felt that Lu Chen was not such a pointless person.

   It's obviously a 37 beats/min ECG, so why do you ask this?

   on the podium.

   Liu Jun stared at Lu Chen closely, then he seemed to think of something, and immediately lowered his head to look for something, "Shuqing, where's the patient's electrocardiogram?"

   Zhang Shuqing glanced at Liu Jun strangely, and whispered, "I have a copy here."

  Liu Jun took the electrocardiogram and read it carefully.

  …

   Under the podium.

   The voices of the crowd are endless.

   Many people saw Lu Chen's face and thought he was a little strange.

   "Which ward is he a doctor? Why haven't I seen him!"

   "I haven't seen it before, so it's not an intern from somewhere, right?"

   "Hey, I heard that Director Zhang Shuqing is accepting doctoral students this year, but you didn't hear him, Director Zhang just called out his name!"

   "Hey, that's right! It's called Lu or something..."

Seeing that Liu Jun and Zhang Shuqing on the stage did not speak, Lu Chen paused and continued: "Some doctors may think that this is not a simple sinus bradycardia, and it can be solved perfectly after implanting a pacemaker. problem, but..."

   He paused and looked around the crowd, "If we distract our attention a little at this time, pay attention to the sharp waveform on the T wave in lead V1 of this electrocardiogram..."

  T wave in lead V1?

   Everyone heard Lu Chen's voice and looked over at the place he reminded.

   However, the graphics in the PPT on the podium are rather blurry, and you can't see anything unusual.

   Only those doctors with copies of electrocardiograms in their hands slowly discovered the difference.

   Director Qin suddenly stood up and looked back at Lu Chen in surprise, "Doctor Lu, you mean the T wave in lead V1, not the T wave?"

   "Yes, not a T wave!" Lu Chen smiled and nodded.

  T wave, not T wave?

What does it mean?

   Everyone's mind was full of mud.

   The conversation between Lu Chen and Director Qin seemed to be encrypted.

   Everyone can't understand!

  …

   on the podium.

   Liu Jun heard the conversation between the two, and when he looked at the electrocardiogram again, a flash of surprise flashed in his eyes.

  T wave, not T wave?

   Such a small detail that is easily overlooked was actually discovered by the doctor in front of him? !

   He whispered to Zhang Shuqing beside him, "Which ward is he a doctor? New here this year? Do you know him?"

   Zhang Shuqing immediately replied: "Director, he is the doctoral student I just recruited this year, Lu Chen."

  Liu Jun was stunned for a moment, then laughed, "Well done! It's really a hero! This time the big discussion in the department is really right."

   Zhang Shuqing is not sure why.

   He looked at the electrocardiogram and found nothing unusual.

   But seeing Liu Jun's attitude change, it must be related to Lu Chen.

   The doctors under the podium also saw the change in the expression of the chief director Liu Jun.

   Combined with what Director Qin just said, everyone began to re-examine Lu Chen's words.

   More and more people are looking for copies of electrocardiograms.

   "Shuqing, can you zoom in on the electrocardiogram on the PPT to make it clearer to everyone."

   The smile on Liu Jun's face was very bright. After Lu Chen's advice just now, he had already seen the essence of this electrocardiogram.

   "Okay, Director."

   Zhang Shuqing nodded slightly and immediately began to operate on the stage.

  …

  The electrocardiogram on the PPT gradually enlarged, and all the doctors present could clearly see the T wave in lead V1.

  The crowd began to whisper.

   "The shape of this T wave is really different from the normal one! It's very sharp, it's really not a T wave!"

   "Yes, not T waves, nor QRS waves, nor U waves!"

   "It's nothing, shouldn't it be an interference wave?"

   "Have you seen this kind of interference wave? I don't think it is an interference wave..."

  The people present here are the backbone of each ward. After Lu Chen's reminder, they immediately discovered something wrong with the T wave of the electrocardiogram.

   On the stage, Zhang Shuqing was stunned.

   He understood at once, and murmured, "This is not a T wave, nor is it any other waveform."

   "Then there is only one possibility left!" Zhang Shuqing looked at Lu Chen in surprise, "That is the P wave!"

  …

   Most of the doctors present suddenly realized at this moment.

   The way they looked at Lu Chen started to change!

   "Doctor Lu, please continue to explain it to everyone."

   On the stage, Liu Jun looked at Lu Chen, and the corners of his mouth curled up.

"Okay, Director." Lu Chen replied, holding the electrocardiogram in his hand, his tone was unhurried, "I believe all teachers should have discovered that, judging from the T wave on this lead V1, it is not real T waves, but P waves!"

   "And this P wave is not the same as the normal P wave, so it must be an early morning."

   Following Lu Chen's voice, everyone began to re-examine the electrocardiogram in front of them.

   As you can see, the shape of this P wave is really different from the normal P wave!

Lu Chen continued: "There is no QRS wave behind Fang Zao, which means Fang Zao arrived very early, encountered the refractory period of the atrioventricular node, and has not been passed down. The current heart rhythm is called sinus rhythm and atrial early doublet rhythm, which is just atrial early. Not uploaded."

   "Fang Zao didn't go down, but it has a compensatory pause."

   "The appearance of compensatory intervals resulted in a slowing of the heart rate and also caused the patient's symptoms of fatigue."

  Lu Chen's explanation was very clear, and everyone present understood the essence of this electrocardiogram.

   However, there are always people who disagree.

   Jiao Jingqiu raised his hand.

  Lu Chen was slightly taken aback, but still handed the microphone to her.

   "Doctor Lu, your analysis was correct just now. But after so much analysis, isn't the final conclusion a slow heart rate? Is it different from what we analyzed? Why do you say it's a tachyarrhythmia?"

   "I think I can answer you this question."

  Lu Chen was about to answer when Director Qin in the front row suddenly stood up. He stared at Jiao Jingqiu with a smile.

   All eyes were focused on him again.

   "If you look at it from the perspective of QRS or systole, it is undoubtedly a slow arrhythmia."

   "But from the point of view of the P wave, the frequent arrhythmia should be a rapid arrhythmia!"

   "If we analyze from the causal relationship, the slowed heart rate is the result, and the frequent occurrence of early morning sickness is the cause!"

   Speaking of this, Director Qin's tone paused slightly, his eyes turned to Lu Chen, his eyes softened, "I think, this is what Dr. Lu just said, tachyarrhythmia!"

   If you are interested in this ECG, I will post it
