   "Well. 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 fix it, so we set up an isolation belt to cut it off to drive left atrial electrical activity. Target monitoring can be more accurate in determining whether ablation is successful. We can learn from this method.”

   Atrial fibrillation caused by pulmonary veins is similar to a scar area, and the ablation of a single pacemaker by ordinary methods is not effective. Surgical improvements were performed in all four pulmonary vein openings to do ablation and block, and the effect was doubled. The abnormal area during ablation is detected by a three-dimensional three-dimensional voltage mapping system. Specifically, it is detected by each catheter placed in the heart cavity, and then a three-dimensional image is synthesized by special software to help the doctor identify and guide the doctor to perform ablation in the abnormal potential area. The lesioned pulmonary vein area treated by ablation will change from high voltage to low voltage, thus confirming that the ablation is effective.

"I understand the steps you are talking about. But in pulmonary vein isolation, we first use electrophysiological examination to determine that the ectopic pacing originates from the abnormal area of ​​the pulmonary vein muscle sleeve before performing ablation. The three-dimensional target verifies that during the ablation effect, the patient always belongs to the During an attack. You can\'t get around the irritant lesion. Are you still thinking of hitting your luck on the area you\'re deliberating?"

  Others at the scene heard that the chief knife was getting more energetic the more he discussed academics with Xie.

  Ping Huai looked at Doctor Wang Che, only remembering that this guy doesn\'t seem to like to talk non-stop on weekdays. Besides, this is talking to a young junior, and at first Doctor Che\'s tone was arrogant and questioning. Well now, maybe he didn\'t notice it himself. Unconsciously, he did not regard the other party as a junior but a peer, and the academic words were blunt.

   The discussion on the scene is about to turn into a situation where the two big brothers are arguing. - This is the only thought that can flash in everyone\'s mind.

   It was later confirmed that the taste was right.

Xie Wanying said: "Teacher, you can say that I bet. According to what I said before, I guessed based on the patient\'s cardiac magnetic resonance results and the first episode of the patient I observed. I guessed not the lesion area, but the The normal area. Because I said that the lesion area is disordered, it is meaningless to tangle. What I want to analyze is the orderly normal area.”

   "You are not stimulated, can you tell what is normal and what is not normal?"

"According to the structure of the heart, the blind spots must be disordered, and the non-blind spots are ordered. The scars may or may not grow blindly. For example, what I observed in today\'s surgery, the compensatory thickening has some There are some who don\'t grow blindly. For compensatory thickening that doesn\'t grow blindly, doctors have always had a more accurate prediction for it and can deal with it, right?"

   Doctor Che\'s throat got stuck.

  Other people at the scene heard this, and it was obvious that Doctor Che showed signs of defeat in the first round of this debate similar to the dialogue between the big brothers.

  The latter wave pushes the former wave, and the younger generation outperforms the predecessor in an academic debate. There is no need to be surprised. There are many in the academic circle. Once does not mean all.

   Let the seniors and teachers at the scene, including those who know Xie and are familiar with Xie, should be surprised by the following.

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