Ablation is the procedure recommended for the long-term management of atrioventricular nodal reentry tachycardia (AVNRT) and atrioventricular reentry tachycardia (AVRT). This technique is focused on interrupting the electrical pathways that cause these types of tachycardia. During catheter ablation, an electrophysiologist employs radiofrequency energy or cryoablation to selectively destroy the tissue responsible for the abnormal conduction pathways.

The effectiveness of ablation in managing these conditions is well established, with a high success rate and a low rate of complications. Following the procedure, many patients experience a significant reduction in or complete resolution of symptoms and episodes of palpitations or tachycardia.

In contrast, cardiac resynchronization therapy is primarily used for patients with heart failure and specific types of heart rhythm disorders, rather than for AVNRT or AVRT. Coronary artery bypass grafting focuses on revascularization in cases of coronary artery disease and is not directed at heart rhythm issues. The implantable cardioverter-defibrillator is utilized to prevent sudden cardiac death in patients at risk due to life-threatening arrhythmias and is not a first-line treatment for AVNRT or AVRT.
