"If you think about it carefully, pathological things are out of the normal healthy order, just like a tumor growing randomly."

"Yeah. What you said makes sense."

"Teacher, you should know that pulmonary vein atrial fibrillation, the pulmonary vein ectopic pacemaker area that causes atrial fibrillation is also very disordered. We can't deal with it, so we set up an isolation belt to cut off its drive to the left atrial electrical activity. During the period, if three-dimensional measurement and monitoring are used, it can be more accurate in determining whether the ablation is successful. We can learn from this method."

Atrial fibrillation caused by pulmonary veins is similar to scar areas, and the effect of ablation of a single pacemaker point using ordinary methods is not good. The surgical improvement is to ablate and block all four pulmonary vein openings, which doubles the effect. The abnormal area during ablation is detected by a three-dimensional voltage mapping system. Specifically, the various catheters placed in the heart cavity are tested and then a three-dimensional image is synthesized using special software to help doctors identify and guide doctors to ablate in the area of ​​abnormal potential. The diseased pulmonary vein area that has been ablated will change from high voltage to low voltage, thus proving that the ablation is effective.

"I understand the steps you mentioned. But in pulmonary vein isolation, we first use electrophysiological examination to confirm that the ectopic pacemaker originates from the abnormal area of ​​the pulmonary vein muscle sleeve before performing ablation. During the period of three-dimensional mapping to verify the ablation effect, the patient is always in the attack period. You can't avoid stimulating the lesion. Are you still thinking of taking a chance on the area you are considering?"

Other people at the scene could tell that the surgeon became more and more excited as he discussed academic matters with Xie.

The people in Pinghuai looked at Dr. Che, and only remembered that this guy didn't seem to like to talk a lot on weekdays. Moreover, he was talking to a young junior. At the beginning, Dr. Che's tone was arrogant and questioning. Now it's good, maybe he didn't realize it. Unconsciously, he didn't regard the other party as a junior but as a peer, and he was speaking directly in academic terms.

The discussion was about to turn into a debate between two big men. This was the only thought that flashed through everyone's mind.

Later it was confirmed that the taste was indeed correct.

Xie Wanying said, "Teacher, you can say that I'm gambling. As I said before, I'm speculating based on the patient's cardiac MRI results and the patient's first attack scenario that I've observed. I'm not speculating on the lesion area, but the normal area. Because I said, the lesion area is disordered, and it's meaningless to worry about it. What I want to analyze is the ordered normal area."

"Without stimulation, can you tell what is normal and what is abnormal?"

"According to the structure of the heart, the blind areas are definitely disordered, and the areas that are not blind are orderly. Scars can grow blindly or not. Just like what I observed during the surgery today, compensatory thickening can grow blindly or not. For compensatory thickening that is not blind, doctors always have a relatively accurate prediction and can deal with it, right?"

Doctor Che felt a lump in his throat.

When the other people at the scene heard this, it was obvious that Dr. Che was showing signs of defeat in the first round of this debate that was similar to a conversation between big men.

The younger generation is better than the older generation. There is nothing surprising about an academic debate, as there are many in the academic circle. One time does not represent all.

What should have surprised the seniors and teachers present, including those who knew Xie, was the following.

Think about what young medical students generally think about at this stage?
