Minimizing for Maximum Benefit: An Illustrative Case-Series of Atrial Only Leadless Pacing.

Leadless pacing technology now includesdedicated atrial helix-fixation leadless pacemakers (LPs), expanding theapplication of leadless devices for patients with sinus node dysfunction andatrioventricular block during sinus rhythm. This first reportedcase-series of atrial LPs describes and discusses the potential use-casescenarios of recently approved helix-fixation atrial LPs. The article highlights important concepts regarding their use, including implantationtechniques, programming, battery conservation, and the low rate of progressionof AV block in patients implanted with AAI(R) pacemakers.
