  The 3D mapping software is running. It is not uncommon for such a method to be used in scar ablation. It\'s just that the risk of stimulation is avoided by not stimulating it now.

   The current operation is to verify whether Xie’s academic hypothesis is correct or not. The teachers present also paid attention to this.

   At this time, no one can easily say who is lucky, after all, there have been academic debates.

  Ablation of the isolation tape begins. In addition to the location of ablation, the energy used for the depth of ablation needs to be carefully considered by the doctor, to avoid burning through the perforation or not burning enough depth to cut off the abnormality.

   Xie Wanying\'s advice to the teacher is that the power is not consistent, there are highs and lows.

  The surgeon stopped talking for a long time, and followed her instructions carefully and slowly operated according to her own observations and inferences. Explain that it is not easy to do what she said. The nurse came up and wiped the sweat on the forehead of the chief knife.

   After the isolation tape is done, the operation time has passed an hour. This time is faster than the surgeons expected. It seems that it takes a lot of time to discuss and discuss, but in the next operation, because the path is clear, it saves time.

   to the most critical step. After the ablation is completed, a drug test will be done to verify the effect.

   "I\'ll push the medicine." Dai Ronghong volunteered.

   Absolutely trusting her old friend\'s abilities, Doctor Che nodded.

   Drug tests include isoproterenol test and ATP test. Like isoproterenol, it increases the heart rate, shortens the effective refractory period of cardiomyocytes and increases the excitability of slow responding cells, which in turn easily induces tachycardia. The specific usage is to add two milligrams to 100 milliliters of normal saline for intravenous drip, at a slow to gradually fast speed to a certain rate.

Everyone held their breath during the    challenge test. If the ablation fails, the patient needs to be rescued at any time. The people in the operating room were very nervous at first. The nurse prepares rescue equipment. Dai Ronghong put all the rescue medicines that could be used immediately first, just in case.

  The defibrillator may fail again even if the defibrillator is placed at the head of the bed. The temporary pacemaker was called by Dr. Che and placed on the instrument table for standby.

  The eyes of everyone inside and outside the operating room almost wanted to stick to the various values ​​on the instrument and stare at them.

The    second hand ticks on the wall clock on the white wall.

  Degrees and seconds are like years.

   After dripping almost half the bottle of liquid, everyone finally realized that the patient had no tachycardia, and the occasional atrial tachycardia that the patient had previously had disappeared.

  Three-dimensional software monitors the heart over and over again, and no abnormal high pressure area is found.

   "Do another ATP test." Seeing that it was too successful, the doctors couldn\'t believe their eyes.

  EPS is an electrophysiological examination. The mechanical stimulation on the endocardium as mentioned earlier induces tachycardia. The ATP test is also a drug test, and the method of administration is intravenous bolus.

   After repeated verification, the ablation effect was excellent. The big stone in the hearts of all doctors was removed.

   happily went out to inform the family. When Dr. Che walked out of the operating room, he shouted, "Dr. Xie. I\'ll treat you to dinner."

   "No, I invite her to eat."

   When everyone realized who said this sentence, Zhao Zhaowei and his classmates: Scared?

   Cao Yong and the three of them: Father, you?

   Thank you for your support! ! Good night dears~
