RADIOFREQUENCY ABLATION FOR INAPPROPRIATE SINUS TACHYCARDIA FOLLOWINGSUCCESSFUL ABLATION OF ATRIOVENTRICULAR NODAL REENTRANT TACHYCARDIA

Inappropriate sinus tachycardia is an uncommon clinical problem that m ay be refractory to medical management. It has been described after ra diofrequency ablation of other supraventricular tachycardias. We descr ibe a case of successful ablation of inappropriate sinus tachycardia t hat occurred late after ablation of the slow pathway for atrioventricu lar (AV) nodal reentrant tachycardia. Markers for successful ablation, as well as potential complications of this procedure, are discussed.
