Returning to '90s, She Became Famous in Major Surgical Fields

Chapter 2740 : I can only ask her again

  This causes the electrical signal to pass through the scar area and can only rely on this point of cardiomyocytes to support the electrical signal channel. Just like a boat passing through a channel with little water, the speed will inevitably become very slow. Placement in the electrical conduction of the heart is called conduction block. The conduction block causes the electrical signal to be chaotic and the heart arrhythmia occurs.

  Is it possible to ablate the ectopic pacing point of scar tissue exactly called ectopic pacing area? Yes there is.

Medical research has found that the electrical signal channel in the scar tissue is narrow like a strait. In medicine, it is called the isthmus, and the isthmus is called a labyrinth in the scar tissue. The medical term is called the reentry ring. There is an exit.

  The doctor can wait for the rabbit to find the exit to fuse it. Because scars are generally used as demons to cause atrial tachycardia and ventricular tachycardia, this is the exit point. On the one hand, the electrical signal in this place can return to excite the scar, and on the other hand, it can be discharged to the ventricle and atrium to cause arrhythmia atrial tachycardia.

  Theoretically, if the doctor follows the method mentioned above, the arrhythmia caused by the scar should be successfully cured. Why do doctors think scars are more of a headache?

Here comes the problem, the reentrant loop and exit for scar tissue-related VT and atrial tachycardia are variable, and the exit changes. You remove it, next time it becomes another exit. It is conceivable that Dr. Che's misrepresentation of finding an ectopic pacemaker is a fallacy that cannot be realized.

  Scar tissue ablation, the recurrence rate of surgery is terrible, nearly half of the patients will recur after one year. The risk of surgery is as high as Xie said. When you can't find the lesion, you stimulate the disease to become a demon in seconds. Your doctor doesn't know how to rescue in a daze, and the patient has to die. In such an operation, the mortality rate is as high as one to three percent, and one to three per 100 people die, which is horrible.

   In order to avoid this high risk, doctors may take another approach.

   "ICD implantation can be considered." Director Gao said.

  ICD is a therapeutic device that integrates cardiac pacing and electrical cardioversion. Like a pacemaker, electrodes are placed in the heart, and a small machine is buried in the patient's body. Once the patient suffers from malignant arrhythmia, the machine will automatically monitor and automatically give electrical cardioversion. If the heart rate is too low, pacing will be given directly. Sounds like this is a very good thing.

   "Didn't defibrillation have no effect on him?" Dr. Che remembered that it seemed to be written on the medical record.

Besides, ICD implantation also requires intraoperative stimulation to find the lesion and discharge electrodes, which can at most reduce the postoperative recurrence rate. The most fundamental problem is that ICD implantation is not a cure. Student Wei wants to be a surgeon, and if she has this thing in her body to get a job, she will definitely be discriminated against.

  If the doctor has the ability to ablate and cure him, why bother with this non-curable thing.

The discussion  has long turned into a dead end. Dr. Che found that he could only ask the young Dr. Xie again.

  People blame it on the person who has succeeded in luck, regardless of whether you are young or not, and whether you are lucky or not.

   Doctor Che chased after him and asked, "You can tell me your specific method and basis."

   Here Xie Wanying needs to explain the source of her thoughts: "I thought I had a good understanding of the heart after anatomy. Until today, it was found during the operation that the compensatory thickening of the myocardium was not completely ordered. Scarring is difficult because it is disordered."
