Indications for radiofrequency ablation

Only a healthy heart can guarantee the health of your body. So when there is a problem with your heart, many patients want to choose radiofrequency ablation surgery to treat their heart disease as soon as possible in order to ensure their health. So if you want to fully understand the indications of radiofrequency ablation, the answer is given below. Many patients with this disease can have a comprehensive understanding of it.

1. Atrioventricular reentrant tachycardia (preexcitation syndrome): There is a congenital "accessory pathway" between the atrioventricular space and the catheter radiofrequency will "cut off" the access pathway, and tachycardia or preexcitation waves will no longer exist.

2. Atrioventricular nodal reentrant tachycardia: The atrioventricular node forms a "dual pathway". Under appropriate conditions, the current runs rapidly in the reentrant loop formed by the two pathways, causing tachycardia. Catheter radiofrequency ablation of the slow pathway leaves only the fast pathway, and tachycardia no longer has the conditions for an attack.

3. Atrial flutter (AFS): Atrial flutter is a condition in which a large loop exists in the atria, in which the electric current keeps circling around. The atria beat at 250-350 beats/minute, and the ventricles generally at 150 beats/minute. Catheter radiofrequency can destroy the loop, causing bidirectional current block, thereby curing AFS.

4. Atrial tachycardia (AT): AT is a condition in which there is an abnormally rapid "excitation point" in a certain part of the left or right atrium that releases electric current or a small reentrant movement in the atrium; electrophysiological examination maps the ectopic "excitation point" or reentrant circuit, and ablation is performed to achieve a cure.

5. Ventricular premature contraction (premature beat): mainly used for frequent ventricular premature beats with obvious clinical symptoms from a single source; often caused by ventricular "excitation focus"; after mapping and ablation of the ectopic excitation focus, the ventricular premature beat can disappear.

The above introduces the indications for radiofrequency ablation. For many patients, this disease must not be ignored, because if it is not treated as soon as possible, it will seriously affect the health of your heart and the health of your entire body. After fully understanding the indications, in order to recover, you should choose this method of treatment as soon as possible.
