Initial Capture Failure With Delayed Resolution in Atrial Leadless Pacemaker Implantation: A Case of <scp>ATTR</scp> Amyloidosis With Sinus Node Dysfunction

ATTR amyloidosis patient with initial atrial capture failure showed delayed threshold improvement over time. Stable current of injury and impedance guided expectant management, avoiding unnecessary device repositioning while achieving successful outcomes.
