Late Outcomes of Surgical Ablation for Inappropriate Sinus Tachycardia.

ABSTRACT:

Background

Inappropriate sinus tachycardia (IST) is a rare clinical disorder characterized by an elevated resting heart rate and an exaggerated rate response to exercise or autonomic stress. Pharmacologic therapy and catheter ablation are considered first-line treatments for IST but can yield suboptimal relief of symptoms. The results of surgical ablation at our center were reviewed for patients with refractory IST.

Methods

Between 1987 and 2018, 18 patients underwent surgical sinoatrial (SA) node isolation for treatment-refractory IST. All 18 patients had previously failed pharmacologic therapy, and 15 patients had failed catheter ablation of the SA node.

Results

Ten patients underwent a median sternotomy, and 8 patients underwent a minimally invasive right thoracoto
