ablation

[ab-la´shun]

1. separation or detachment; extirpation; eradication.

2. removal, especially by cutting with a laser or electrocautery.

catheter ablation radiofrequency ablation.

endometrial ablation removal of the endometrium; methods used include radiofrequency, electrical energy, lasers, and hot and cold liquids.

radiofrequency ablation (radiofrequency catheter ablation) destruction of an accessory conduction pathway or other troublesome area of dysrhythmia by means of unmodulated high frequency alternating current delivered by a bipolar or unipolar catheter. The current causes heat with tissue destruction and formation of scar tissue to block the pathway or dysrhythmic area. Transvenous radiofrequency ablation has been successful in treatment of supraventricular tachycardia and is an attractive option to surgery. Called also catheter ablation.

Radiofrequency ablation (RFA)

A technique for removing a tumor by heating it with a radiofrequency current passed through a needle electrode.

Therefore, in a case of sick sinus syndrome when the patient's symptoms cannot be attributed to the bradycardia, but to the tachyarrythmic episodes, it is most efficient to treat the patient's PSVT by radiofrequency ablation, rather than using cardiac pacing or antiarrhythmic drugs.
