This results in electrical signals passing through the scar area only barely relying on the cardiomyocytes to support the electrical signaling pathways. Just like a ship passing through a channel with little water, its speed will inevitably become very slow. Placed in the electrical conduction of the heart is called a conduction block. The conduction block causes the electrical signal to become chaotic and lead to cardiac arrhythmia.
Is it possible to ablate the ectopic pacing site that scar tissue is accurately called the ectopic pacing area? Yes there are.
Medical research has found that the electrical signal channel in scar tissue is narrow like a strait. In medicine, it is called the isthmus. The isthmus wraps around in the scar tissue and is called a labyrinth. There is an exit for running out.
Doctors can sit back and wait to find the right exit and fuse it. Because generally scars act as monsters to cause atrial tachycardia and ventricular tachycardia 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, discharge to the ventricle and atrium to cause cardiac arrhythmia, atrial tachycardia and ventricular tachycardia.
Theoretically speaking, if the doctor follows the method mentioned above, he should be able to successfully cure the arrhythmia caused by the scar. How could the doctor feel that the scar is more of a headache.
Here lies the problem. The reentry loop and outlet of scar tissue-related VT are variable, and this outlet changes. You cancel it, next time it will become another exit. It is conceivable that Dr. Che's false statement that finding an ectopic pacemaker is a fallacy that cannot be realized.
For scar tissue ablation, the recurrence rate of surgery is terrible, and nearly half of the patients will relapse after one year. The risk during the operation is as high as Xie said. When you can't find the lesion, the disease is stimulated and becomes a demon in seconds. Your doctor doesn't know how to rescue it in a daze, and the patient has to die. The mortality rate in such an operation is as high as 1 to 3%, and 1 to 3 deaths per 100 people. It is not scary.
In order to avoid this high risk, doctors may take another approach.
"You can consider ICD implantation." Director Gao said.
ICD is a treatment device that integrates cardiac pacing and cardioversion. Like a pacemaker, electrodes are placed in the heart, and a small machine is buried in the patient's body. Once the patient has a malignant arrhythmia, the machine automatically monitors and automatically administers electrical cardioversion. If the heart rate is too low, pacing is given directly. It sounds like this is good stuff.
"Didn't electric defibrillation have no effect on him?" Doctor Che remembered what seemed to be written in 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 for you. The most fundamental problem is that ICD implantation cannot be cured. Student Wei wants to be a surgeon, so he will definitely be discriminated against if he goes to work with this thing in his body.
If the doctor has the ability to ablate and cure him, why bother to do something that doesn't cure him.
Discussion up to now, has long turned into a dead end ahead. Dr. Che realized that he could only ask this young Dr. Xie again.
People blame it on the person who was lucky enough to succeed, regardless of whether you are young or not, and whether you are lucky or not.
Dr. Che chased after him and asked, "Please tell me your specific method and basis."
Here, Xie Wanying needs to explain the source of her thoughts: "I used to think that I knew a lot about the heart through anatomy. Until today, I found that the compensatory thickening of myocardium was not completely orderly. The scar is difficult to deal with because it is disorderly."
