MTL - I Can See Health-Chapter 42 ECG battle (middle)

  Chapter 42 ECG battle (middle)

   Five ECGs were circulated to each other.

  Lu Chen is very interested in ECG.

   During his internship, he taught himself electrocardiogram for a long time.

   However, it is easy to get started with ECG knowledge, but extremely difficult to master.

   ECG, a small piece of paper, records the changes in the electrocardiogram vector on the surface of the human body.

The magic of    is that through this trivial image, people can gain insight into various heart-related diseases, including arrhythmia, coronary heart disease, myocarditis, pericarditis, etc.

   Even a small change corresponds to the occurrence of a certain disease.

  Small and careful electrogram, contains a big universe!

  Lu Chen has learned from the present, and thinks that he has only learned the surface.

   Everyone whispered, each discussing the diagnosis of the electrocardiogram.

  Lu Chen flipped through the five electrocardiograms.

   Two of them.

   is the most common arrhythmia ECG in cardiology department, which are frequent premature ventricular contractions and atrial fibrillation.

   There is also an electrocardiogram of acute inferior wall myocardial infarction.

   As for the other two, Lu Chen didn't see the diagnosis right away.

   The circulation time was over, and the five electrocardiograms returned to Lin Cui.

   She arranged the five electrocardiograms one after another and placed them on the table.

   "Okay, then I'll start testing everyone."

  Lin Cui looked around the crowd and picked out the first electrocardiogram.

   "Student, please answer first, what is the diagnosis of this electrocardiogram? The reason should also be given."

   The guy named by Lin Cui was a quiet and quiet boy. He was a regular training student in Lin Cui’s group. This year is his second year of regular training.

   "The QRS wave in this electrocardiogram is wide and deformed, which should be premature ventricular contractions. Because there are four premature beat waves with the same shape, it should belong to frequent single-source premature ventricular contractions."

  Lin Cui nodded with a smile and said, "Well, it seems that you usually study hard. This picture is indeed of frequent premature ventricular contractions. Then I will ask the next question, which is also about this electrocardiogram."

   "Since you know that premature ventricular contractions occur frequently, let's talk about the origin of premature ventricular contractions in this picture."

   As soon as he finished speaking, there were whispers around him.

   Origin of ventricular premature beats?

   This relates to the anatomical location of the heart.

   But all the students here are just entering the clinic, and few people pay attention to the anatomical position of the heart.

   This question is beyond the outline!

  Men Gai Pearson scratched his head, showing an embarrassed look.

   "Director Lin, I, I won't."

  Lin Cui smiled, then turned to look at another intern.

"how about you?"

   The intern was startled and waved his hand quickly, "Director, neither do I."

  Everyone talked a lot, but no one answered the point.

   "Mr. Lin, this should be a premature beat originating from the apex of the heart."

  Suddenly, He Sirong on the side spoke slowly.

  Lin Cui smiled, put the electrocardiogram in front of He Sirong, and said, "Why?"

   "I have recited a similar formula. The main wave of the QRS complex in leads II, III and aVF is downward, and the main wave in leads aVL and aVR is upward, which is a premature beat originating from the apex." He Sirong smiled.

   "Well, not bad." Lin Cui nodded with satisfaction, "The deeper reason is because of the electrocardiogram vector, but you can answer this, it's pretty good."

  He Sirong is Lin Cui's graduate student.

   She was able to answer this question, which made Lin Cui's face glow.

   "Okay, let's look at the next one."

   This electrocardiogram was just taken out, and everyone had a "I know" smile on their faces.

   This is an electrocardiogram of acute inferior wall myocardial infarction, typical of ST-segment elevation in leads II, III, and aVF.

  Lin Cui picked a graduate student who was rotating in the Department of Cardiology.

   "Excuse me, which root is the culprit vessel in this electrocardiogram of acute inferior wall myocardial infarction?"

What? Criminal blood vessels?

When   Lin Cui's question came out, everyone was stunned.

   She directly gave the diagnosis of acute inferior myocardial infarction, but instead asked the location of the culprit vessel.

   Good guy, he doesn't play cards according to the formula at all.

   Director Lin Cui is really "insidious" and "cunning"!

   "This..." The boy scratched his ears, "Right crown or circumflex?"

  Lin Cui smiled lightly, "You little guy, you have stated both possibilities, I just let you judge which of the above?"

   "Director Lin, I won't..." The boy pouted, he is not a graduate student of Cardiology, so what do you know?

   "Who knows?"

  Lin Cui looked at everyone.

   Seeing that no one answered, she glanced at He Sirong.

  He Sirong understood, cleared his throat, and said, "Mr. Lin, ST segment elevation STIII>STII in this picture, it should be right coronary occlusion."

   Everyone looked at Lin Cui's expression and found that she was smiling.

   It seems that He Sirong is right again!

  Lu Chen looked at He Sirong, he didn't expect this girl to be quite powerful, her electrocardiogram level should have surpassed most of the people present.

  It is not easy to have this level in the first year of research.

   "Okay, then let's look at the third ECG."

  Lin Cui took out the third electrocardiogram.

   This time, everyone did not dare to comment easily.

  In case, Lin Cui asked another "exotic" question...

  Lu Chen looked at this electrocardiogram.

   is very simple, it is an electrocardiogram of common atrial fibrillation.

   In cardiology, the electrocardiogram of atrial fibrillation and premature beats should be the most common and easily recognizable.

   "You answer."

  Lin Cui raised her hand and pointed at Ke Yue next to Lu Chen.

  Ke Yue was startled and walked forward slowly.

   "What is the diagnosis of this ECG?"

   This time, it was a normal question.

   But Ke Yue lowered her head and looked at the electrocardiogram at a loss.

   I didn't utter a word for a long time.

   for a long time.

  The smile on Lin Cui's face has disappeared, replaced by a serious look.

   "Can't you see what kind of electrocardiogram is this?"

   Ke Yue's face was flushed red to the base of her ears.

   still didn't say a word.

  Lu Chen frowned. He was standing beside Ke Yue. Although he wanted to help, he couldn't give such an open and honest reminder.

   "I remember, you seem to be Director Li's student, right?"

   Ke Yue nodded silently.

   "But can't you even see such a simple electrocardiogram?"

   "Look carefully again! See if there are any p waves!"

   Lin Cui's volume increased a bit, and the office suddenly became silent.

   "Can't you see it yet? Then tell me, what is this electrocardiogram!"

   Lin Cui just finished speaking, and everyone present glanced at each other, and then said the word "atrial fibrillation" in unison.

  …

   In the ward, Sun Guoguo has already checked the room.

  Lu Chen and Ke Yue haven't come back, and Dong Hao, who was sent out, hasn't come back either!

  Sun Guoguo led the crowd back to the doctor's office. Seeing everyone gathered around, Director Lin was giving a lecture, he suddenly realized.

   "Doctor Sun, you came back just in time."

   Sun Guoguo, who had just walked into the doctor's office, was stopped by Lin Cui.

   "You have to teach this kid well!"

  Sun Guoguo looked in the direction Lin Cui pointed, it was Ke Yue with his head down.

   "This child can't even recognize the electrocardiogram of atrial fibrillation!"
