Efficacy of intentional permanent atrial pacing in the long‐term management of congenital long QT syndrome

Cardiovascular Electrophysiology, 2020
Unfortunately, some patients with long QT syndrome (LQTS) experience breakthrough cardiac events (BCEs) despite maximal therapy. Small studies have shown that refractory LQTS cases may benefit from intentional permanent atrial pacing (IPAP).
