The development of non-pharmacological therapy in tachyarrhythmia

After CAST study, non-pharmacological therapy for the tachy-arrhythmias have made much developments in especially radiofrequency catheter ablation and implantable cardioverter defibrillator (ICD). To assess the short-and long-term results of catheter ablation for supraventricular tachycardia (SVT), especially on the delayed success, we investigated 219 pationts with supraventricular tachycardias in Yamaguchi University Hospital. The success and recurrences rates of ablation for SVTs were similar to those reported by some investigatiors. The recurrence rate after the discharge was relatively higher in patients with delayed success or with second success for ablation. In catheter ablation to isthmus between the tricuspid valve and inferior vena cava for common atrial flutter, the early recurrence was relatively rare, the delayed success was relatively high. The system of ICD has been developed in the size , life-span, threshold of VF, and lead system. The indications of ICD will take wider than old, especially, the prophylactic therapy with ICD is allowed. In the near future, the new systems will be associated with ICD
