Interventional arrhythmology deals with the nonpharmacological management of patients with symptomatic arrhythmias. Percutaneous catheter ablation is used to cure patients with arrhythmias due to accessory pathways or AV-node reentrant tachycardia. In patients with drug-refractory sustained, hemodynamically significant ventricular tachyarrhythmias, implantable third generation defibrillators provide an effective therapeutic modality. Our article provides a brief overview of these new therapeutic modalities and summarizes our local experience.
