The surgery was performed step by step according to the steps discussed previously.

The three-dimensional mapping software is running. This method is not uncommon in scar ablation. It's just that it doesn't stimulate now to avoid the risk of stimulation.

At present, this operation is also to verify whether Xie's academic hypothesis is correct and feasible. The teachers present are also paying attention to this.

At this point, no one would easily say that someone was lucky, after all, an academic debate had been conducted.

The ablation of the isolation zone begins. In addition to the location of the ablation, the depth of the ablation and the energy used need to be carefully considered by the doctor to avoid burning through the perforation or not burning deep enough to cut off the abnormality.

The advice Xie Wanying provided to the teacher was that the power was not consistent, some were high and some were low.

The surgeon had stopped talking and was operating very carefully, referring to her instructions and following his own observations and inferences. It was not easy to think and do what she said. The nurse came up and wiped the sweat off the surgeon's forehead.

After the isolation band was made, the operation lasted an hour. This time was faster than the surgeons expected. The discussion seemed to take a long time, but in the following operation, the clear path actually saved time.

Now comes the most critical step. After the ablation is completed, a drug test is needed to verify the effect.

...

...

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

Dr. Che nodded, expressing her absolute confidence in the abilities of her old friend.

Drug tests include isoproterenol test and ATP test. Isoproterenol can increase heart rate, shorten the effective refractory period of myocardial cells and increase the excitability of slow-reacting cells, which can easily induce tachycardia. The specific method is to add two milligrams to 100 milliliters of normal saline and drip intravenously, with the speed starting from slow to gradually fast to a certain rate.

During the stimulation test, everyone held their breath. If the ablation failed, the patient would need emergency treatment at any time. The people in the operating room were very nervous. The nurse prepared the emergency equipment. Dai Ronghong put all the emergency drugs that could be used immediately on the table just in case.

The defibrillator was placed next to the bed, even if the defibrillator might fail again. Dr. Che asked him to put the temporary pacemaker on the instrument table for standby.

Everyone inside and outside the operating room stared at the various values ​​on the instruments with their eyes glued to their chests.

The second hand ticked by on the wall clock on the white wall.

Every second feels like a year.

After dripping almost half a bottle of **, everyone finally realized that the patient was no longer experiencing tachycardia, and the occasional atrial tachycardia that the patient had previously experienced also disappeared.

The three-dimensional software monitored the heart over and over again and found no abnormally high-pressure areas.

"Let's do another ATP test." Seeing that it was so successful, the doctors couldn't believe their eyes and said excitedly, "Let's do an intracardiac EPS test."

EPS is an electrophysiological test, which involves mechanical stimulation of the heart lining to induce tachycardia. The ATP test is also a drug test, and the drug is administered by intravenous injection.

After repeated verification, it was finally concluded that the ablation effect was excellent. All the doctors felt relieved.

He happily went out to inform the family members. When Dr. Che walked out of the operating room, he shouted, "Thank you, Dr. Xie. I'll treat you to a meal."

"No, I'll treat her."

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

Cao Yong and the other three: Father, you?
