Key result
Radiofrequency modification of the sinus node was successful in all 3 patients with drug-refractory inappropriate sinus tachycardia, resulting in satisfactory heart rate control.
Why the study?
Does radiofrequency modification of the sinus node reduce heart rate in patients with drug-refractory inappropriate sinus tachycardia?

Does radiofrequency modification of the sinus node reduce heart rate in patients with drug-refractory inappropriate sinus tachycardia?
Radiofrequency modification of the sinus node is a feasible and effective treatment option for patients with inappropriate sinus tachycardia refractory to medical therapy.
No takes yet. Share an insight, caveat, or question.
Supports feasibility in refractory cases; leaves open confirmation in prospective trials before practice change.
Sparks et al. (1997) conducted a case report in Inappropriate sinus tachycardia (IST) (n=3). Radiofrequency modification of the sinus node was evaluated on 20-30% reduction in the heart rate with normal atrial activation sequence after ablation. Radiofrequency modification of the sinus node was successful in all 3 patients with drug-refractory inappropriate sinus tachycardia, resulting in satisfactory heart rate control.
