Use of Noncontact Mapping and Saline‐Cooled Ablation Catheter for Sinus Node Modification in Medically Refractory Inappropriate Sinus Tachycardia

Background Inappropriate sinus tachycardia (IST) is characterized by heart rate (HR) increase out of proportion to stress level. Radiofrequency (RF) modification of the sinus node (SN) is an accepted treatment modality for medically refractory IST. We describe a new technique using noncontact map…
