The surgery proceeded step by step according to the steps discussed previously.
The 3D mapping software runs. It is not uncommon to use such a method in scar ablation. Just don't stimulate now to avoid the risk of stimulating.
The current operation is to verify whether Xie's academic hypothesis is correct and feasible. The teachers present also paid attention to this point.
At this time, no one is easy to say who is lucky, after all, there have been academic debates.
Ablation of the barrier 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 to cut off the abnormality.
Xie Wanying's opinion to the teacher is that the power is not consistent, there are high and low.
The surgeon stopped talking a long time ago, and carefully followed her instructions plus his own observation and deduction to operate slowly. Explain that it is not easy to do what she said. The nurse came up and wiped the sweat from the chief surgeon's forehead.
After the isolation belt was done, the operation time passed an hour. This time is faster than the surgeons expected. It seems to take a lot of time to discuss and discuss, but in the next operation, because the path is very clear, it saves time.
Now comes 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.
She is absolutely trustworthy in the abilities of her old friend, Dr. Che nodded.
Drug tests include isoproterenol test and ATP test. Like isoproterenol, it will increase the heart rate, shorten the effective refractory period of cardiomyocytes and increase the excitability of slow-response cells, thereby easily inducing tachycardia. The specific usage is to add two milligrams to one hundred milliliters of normal saline for intravenous infusion, and the speed is slow to gradually fast to a certain rate.
During the challenge test, everyone held their breath. 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 first aid equipment. Just in case, Dai Ronghong put up all the first-aid medicines that could be used immediately.
The defibrillator is placed next to the bed even if the electrical defibrillation may fail again. The temporary pacemaker was called by Dr. Che and placed on the instrument table to stand by.
The eyeballs of everyone inside and outside the operating room almost want to stick to the various values on the instrument.
The second hand ticked by the second on the wall clock on the white wall.
Seconds are like years.
After dripping almost half of the bottle of liquid, everyone finally realized that the patient did not have tachycardia, and the occasional atrial tachycardia that had occurred before had also disappeared.
The 3D software monitored the heart again and again, and no abnormal high pressure area was found.
"Do another ATP test." Seeing that it was too successful, the doctors couldn't believe their eyes, and said excitedly, "Another EPS in the heart."
EPS is an electrophysiological examination. The aforementioned mechanical stimulation on the endocardium of the heart induces tachycardia. The ATP test is also a drug test, and the administration method is intravenous injection.
After repeated verifications, it is finally concluded that the ablation effect is excellent. The big stone in the hearts of all doctors was removed.
Going out happily to inform the family members, Dr. Che shouted when he walked out of the operating room: "Dr. Xie. I treat you to dinner."
"No, I'll treat 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
