Why the study?
Does sinus node modification using noncontact mapping and a saline-cooled ablation catheter improve heart rate control in patients with medically refractory inappropriate sinus tachycardia?
Does sinus node modification using noncontact mapping and a saline-cooled ablation catheter improve heart rate control in patients with medically refractory inappropriate sinus tachycardia?
Noncontact mapping combined with a saline-cooled ablation catheter for sinus node modification appears to be an effective technique for heart rate control in medically refractory inappropriate sinus tachycardia.
