<jats:p> <jats:bold>Catheter Ablation.</jats:bold> Catheter ablation for control of cardiac arrhythmias was introduced 20 years ago. Since then, this technique has been applied successfully to virtually all cardiac rhythm disturbances. In this essay, some of the newer applications of ablative techniques for patients with AV nodal reentrant tachycardia, atrial flutter, and atrial fibrillation are emphasized. “AV nodal reentrant tachycardia” may involve a nodofascicular tract. A new classification of atrial flutter is proposed and various causes of atrial fibrillation are discussed.</jats:p>
