What Is Nerve Ablation?

Radiofrequency ablation is through the femoral arteriovenous, internal jugular vein, and subclavian vein. Electrode catheters are inserted into the heart, and electrophysiological mapping techniques are used to find abnormal electrical conduction channels or ectopic beat points in the heart. Resistance myocardial effect is generated in the myocardial tissue, which makes myocardial cells dry and necrotic, and achieves the purpose of treating tachyarrhythmia.

Under local anesthesia, 3 to 4 electrode catheters are passed through the femoral vein,

First through the internal jugular vein or

Radiofrequency ablation treatment is to perform electrode ablation by vascular puncture, sending electrode catheters to specific parts of the heart cavity, looking for abnormal conduction paths of the heart, or the location of ectopic pacing points. Generally, when the number of premature beats in a day is more than 10,000, and the location of the lesion is convenient for catheter operation, radiofrequency ablation treatment can be selected. Pediatric tachyarrhythmia usually requires radiofrequency ablation surgery, which is characterized by a sudden acceleration of the heartbeat and a heart rate of 180-300 beats per minute. There is no other cure except radiofrequency ablation. ^[1]

Arrhythmia may persist for a long time, such as premature beats, most of them will exist for seven or eight years, or even more than ten years, and the pre-excitation syndrome will survive. When a severe arrhythmia occurs, the child's activity is limited and the quality of life is poor. If repeated attacks occur, the heart will enlarge and the heart function will decline after a long time, and it should be treated as soon as possible.

Some arrhythmias, such as premature beats, do not shorten the course of the medication, but only relieve symptoms. Moreover, the drug is toxic. If you continue to take the drug, your child will lose more. Therefore, only when the arrhythmia affects the child's quality of life and physical condition, medication should be used for treatment, and radiofrequency ablation treatment can also be used under appropriate circumstances.

However, due to the characteristics of small blood vessels and small heart in children, the implementation of radiofrequency ablation is difficult and risky, so it needs to be carefully selected. For children with tachyarrhythmia under 3 years of age, try to take medication as much as possible. Radiofrequency ablation surgery can be considered for patients over 3 years of age.
