A technique in which radiofrequency is used to treat life-threatening irregularities in the heartbeat.
Ablation in which an electrode delivers a low-voltage, high-frequency current to cauterize and destroy abnormal tissues. Destruction of electrical conduction pathways in the heart with an intracardiac catheter that removes the abnormal conducting tissues has been used to treat Wolff-Parkinson-White syndrome, atrioventricular re-entrant tachycardia, and other cardiac arrhythmias.
A method employed to eradicate a tumor involves the application of a radiofrequency current through a needle electrode, generating heat that effectively destroys the tumor.
