Recent advances in the treatment of arrhythmias.

Advances in endocardial mapping techniques and ablation have greatly increased the indications for catheter-ablation of supraventricular arrhythmias. Rate or rhythm control is a valid treatment option for patients with atrial fibrillation; however, all patients with one or more risk factors should be treated with oral anticoagulants. The early success rate and long-term cure of atrial fibrillation by radiofrequency catheter ablation continues to increase. The number of centers offering this treatment option has increased substantially. Implantable defibrillator-cardioverters are the primary treatment modality for patients with ventricular tachycardia and their role in primary prevention is also being defined. Future advances in arrhythmia management will include improvements in catheter design and energy sources for ablation, and greater monitoring capacity of implantable devices.
