"You stay here. If any problems arise during the operation and require everyone's brainstorming, you can help think about it." Dai Ronghong said.
Others were totally unprepared for what she said.
The most surprised person was Dr. Che, who immediately asked Dai Ronghong: "Who is she? Is she your colleague in the hospital? She is very young."
Being very young is the point of suspicion.
Dai Ronghong thought about the pitfalls she had made and said to Dr. Che earnestly: "Don't underestimate some young people nowadays."
"Young man, I know that you are getting more and more powerful. How dare I underestimate you?" Dr. Che said, his eyes clearly looking at the young doctor at the competitor Guozhi Hospital.
Shin Youhuan was glanced at by the other side's star doctor, who was also a senior doctor, Dr. Che, and shrugged his shoulders, thinking that he did not dare to underestimate the young people behind him, such as his junior sister.
The operating room was fully staffed. Director Gao was the assistant. There were several assistants on site.
Dr. Che stood in the position of the surgeon and first performed peripheral femoral vein puncture and catheterization. This step was not difficult at all for a skilled and experienced doctor who had performed many operations, and it could be done in a few minutes.

Next is the special point that distinguishes this operation from other interventional surgeries. Various test catheters must be placed into the heart cavity.
The surgeon in charge of the operation, by stepping on the pedals, adjusts the angle of the operating table and the C-arm of the machine, and makes various perspective cross-sectional diagrams to ensure that the electrodes of each catheter are accurately placed in the designated position in the heart. Only when the position is accurate can the measured electrophysiological diagram be accurate.
Xie Wanying followed the others in the control room and saw that Dr. Che was slower than Senior Brother Shen in his movements, like a slow-motion camera, but he would do his best to get it done in one go. This is a characteristic of most older doctors, who are more particular about stability.
Through the pictures, we can see that the catheters are placed into the heart chambers one by one. Specifically, the right atrial catheter is placed in the upper part of the right atrium, and the recorded electrogram is displayed on the electrophysiological software analysis screen, codenamed HRA. The atrioventricular bundle catheter is placed at the anterior inner edge of the right atrioventricular orifice. The position here is closest to the atrioventricular bundle and can record the atrioventricular bundle electrogram most clearly and accurately, codenamed HBE. The right ventricular catheter is placed in the apex of the right ventricle, codenamed RVA. The coronary sinus catheter is placed in the coronary sinus orifice, codenamed CS.
The above catheter is placed through the right atrium to mainly solve the problem of right bundle lesions of cardiac conduction. If the problem of the left bundle is to be solved, it is necessary to penetrate the atrial septum and place the electrode in the left atrium.
Wei’s previous electrocardiogram showed that the problem was mainly with the right bundle, so there was no need to attack the left bundle for the time being.
The surgeon places all electrogram catheters as needed for treatment.
The instrument screen beeped and displayed the electrophysiological data of each catheter. The rows of white lines on a blue background were spectacular.
The surgeon looked at the various graphs and did data analysis.
As mentioned before, electrophysiological analysis is crucial, as it is directly related to the effectiveness of treatment in finding the lesions of patients. Only when this foundation is well established can precise ablation be achieved in the next step.
Seeing this, Xie Wanying recalled that before her rebirth, she had accompanied an acquaintance to a tertiary hospital for an interventional surgery. She had witnessed a case where the surgery lasted from morning to afternoon, and the surgeon had to give up in the end. On that day, the doctor spent almost a whole day looking for the target. He could not analyze where the target was, and based on his limited experience, he vaguely analyzed it and it had no effect after burning it.
This is the most critical technical threshold of this technology.
