   Chapter 415 Ablation failed? (first update)

   The next day.

   The first stage assessment of Huaxia Electrophysiology Training Course has begun.

   All the students were very energetic.

   Because as long as you pass this assessment, you can get the electrophysiological intervention certificate awarded by the Chinese Electrophysiological Society.

   If you fail this time, you can only participate in provincial training courses.

  The certificates awarded by the National Electrophysiology Society and the Provincial Electrophysiology Society are quite different!

   The intervention certificate for this training class is universal throughout the country.

   No one wants to give up this rare opportunity.

   "Lu Chen, have you decided who to choose?"

  Min Xiaobo smiled and leaned in front of Lu Chen, placing a hand on Lu Chen's shoulder.

  The two get along day and night, and they are both students from Jinghua, and they have gotten to know each other a lot.

  Lu Chen smiled. What Min Xiaobo asked was to choose a one-on-one mentor after passing the first-stage assessment.

   "After thinking about it, what about you?" Lu Chen glanced at Min Xiaobo, this guy looks very low-key, but he knows that he doesn't have a strong relationship in the academic circle, and it's not easy to get along.

   "Hey, my previous boss contacted me a professor, Qin Sifeng." Min Xiaobo grinned.

   "Qin Sifeng?" Lu Chen raised his eyebrows and smiled, "Brother Bo, you are not easy, Professor Qin should be one of the best professors in the training class!"

  Min Xiaobo smiled and patted Lu Chen's shoulder, "I am also lucky."

   The two chatted for a few minutes before Qin Sifeng walked into the classroom.

   He looked around the crowd and announced, "The first stage of the assessment has officially started!"

  This assessment is also a clinical practice!

  All people will be drawn by group first. There are three types of surgeries, namely pacemaker implantation, arrhythmia radiofrequency ablation, and ICD implantation.

   Among them, radiofrequency ablation is subdivided into several categories.

   Lu Chen's draw was radiofrequency ablation of arrhythmia!

   This time, Lu Chen was assigned to the First Affiliated Hospital of Kyoto University.

   There are four other people in the same group with him, including Yu Hewei, who has been ranked first!

  …

   Everyone came to the catheterization laboratory of the First Affiliated Hospital of Kyoto University.

   This time, not only did the training course attach great importance to the assessment, but Kyoto University also organized students from the Department of Cardiology to watch it.

  In the classroom outside the catheterization room of the Cardiology Department, a large screen broadcasts the entire assessment process.

  Fang Ruzhang also organized graduate students and regular trainees from the department to watch the game.

   "Yao Jie, go to the cath lab later to watch the game." Fang Ruzhang said with a smile to Yao Jie, who was writing the course of his illness.

   "Mr. Fang, I haven't finished writing the course of my illness." Yao Jie said, in the department, she is still used to calling Ms. Fang.

   "Aren't you going to watch your brother's game?" Fang Ruzhang asked with a smile.

   Yao Jie was stunned for a moment, then reacted and said in surprise, "Senior Brother Lu Chen is coming to us to compete?"

   "Yes." Fang Ruzhang nodded slightly, "It will start in about half an hour."

   "Then I'll write the course of the disease quickly." Yao Jie was startled, and the speed of typing on the keyboard was a little faster.

  …

   Enter the catheterization lab.

   All pre-operative preparations are ready.

The trainees of the    training class are still the first assistants, and are led by a chief surgeon to perform the operation.

   Lu Chen received radiofrequency ablation of premature ventricular contractions, while the others were radiofrequency ablation of atrial fibrillation, radiofrequency ablation of ventricular appeal, radiofrequency ablation of atrial flutter, and radiofrequency ablation of premature atrial contractions.

  Although they are all radiofrequency ablation operations, the difficulty of the operation varies with the patient’s physical condition and electrophysiological state.

  Before the assessment.

   Everyone got all the information of the patient, including electrocardiogram and medical records.

  Lu Chen glanced at the electrocardiogram and knew that it was a premature ventricular contraction originating from the right ventricular outflow tract.

   A very conventional arrhythmia, and the method of ablation is also very simple.

  Suddenly, Lu Chen was confident.

  This kind of ablation surgery, he has trained hundreds of times in the simulated surgery room!

   Following the examiner's order, all the students, including Lu Chen, entered their catheterization labs at the same time.

  This time the operation was performed by five people at the same time.

  …

   In the classroom where he was watching the battle, Fang Ruzhang arrived with a group of students.

   "The assessment has begun!"

   Yao Jie stared nervously at one of the small screens, with the operating room No. 3 marked in the upper right corner.

   Although it was not her who performed the operation, she seemed more nervous than the person who performed the operation.

   "Mr. Fang, is Brother Lu Chen's surgery difficult?" Yao Jie whispered.

   "This..." Fang Ruzhang took a closer look at Lu Chen's operation interface, "It looks like it should be a routine arrhythmia radiofrequency ablation. The premature arrhythmia originates from the right ventricle, so it's not too difficult."

   "Yes." Yao Jie's nervousness eased a bit. With Brother Lu Chen's ability, there must be no problem. She also prayed silently for Lu Chen in her heart.

   Catheter room.

  Lu Chen put on gloves and a hat, and began the interventional operation under the instruction of the chief surgeon.

   At the same time, the chief surgeon also acted as the chief examiner, reminding: "If there is any problem in the operation, please report it to me at any time, and if I find anything wrong, the operation will be stopped immediately."

  Lu Chen nodded, indicating he knew.

   Then, he slowly walked to the patient on his head and began to disinfect and spread towels.

  The first step is still the puncture of the blood vessel.

  Lu Chen's actions were very fast. The speed and success rate of his blood vessel puncture far exceeded the other students present, including Yu Hewei, who had been in the first place!

   in the classroom.

   All the audience stared at the big screen with some surprise.

   "This young man in operating room No. 3 has such a powerful puncture?!"

   "Yeah, it really hit the nail on the head. This speed is faster than our director, right?"

   "Maybe it's luck, I can also hit the nail on the head sometimes!"

  …

   Hearing everyone's discussion, Fang Ruzhang smiled.

   The first time he saw Lu Chen's puncture, he was also shocked.

  This technique and speed are like an imaging machine installed on the eye, and it is punctured into the blood vessel in an instant.

   One or two times may be lucky, but almost every time it is successful, it is not a matter of luck!

   At this point, in the catheter room.

  Lu Chen was also very satisfied with his puncture.

   As one of the first clinical skills he trained, his proficiency in vascular puncture has been infinitely close to 100%.

   This is also thanks to his countless trainings, performing various difficult blood vessel puncture training in the simulated operation room!

  Whether it is a narrow blood vessel or a deformed blood vessel, Lu Chen's puncture can be done in one step!

  After the successful puncture, Lu Chen put the catheter into the part of the right ventricular outflow tract on the side of the free wall.

   The arrhythmia in this patient originated in the outflow tract of the right ventricle.

   Therefore, the most basic ablation method is to place the catheter after the right ventricle and perform discharge ablation, which can permanently ablate premature ventricular contractions!

   After mapping the location, Lu Chen started the ablation operation.

   "Ablation Discharge!"

   After the ablation of the discharge begins, the ventricular ablation disappears quickly during the continuous discharge.

   On the ECG monitoring, the patient's premature ventricular contractions have disappeared, replaced by sinus rhythm (normal heart rhythm).

   In the classroom, the audience was amazed that the operation in the No. 3 operating room was so smooth!

   It takes less than half an hour from the start of surgical disinfection to the end of discharge ablation.

   "Success!" Yao Jie showed a bright smile.

   However, Lu Chen on the stage suddenly felt that something was wrong.

   Less than a minute after he stopped the discharge, the patient's ECG monitoring showed that the room had recovered again!

   A series of wide and deformed QRS waveforms made Lu Chen stunned. (Graphic of premature ventricular contractions, QRS waveform wide and deformed.)

   Ablation of premature ventricular contractions, failed? !
