Supraventricular tachycardia ablation is a minimally invasive medical procedure used to treat supraventricular tachycardia (SVT), a condition characterized by an abnormally fast heart rate originating above the ventricles. The procedure involves the use of radiofrequency energy or cryoablation to selectively destroy or modify the abnormal electrical pathways in the heart responsible for the rapid heart rate, thereby restoring normal heart rhythm.
