Introduction: Leadless pacemakers (LP) are increasingly utilized in pts with bradycardia and may be associated with better outcomes compared to right ventricular pacing (RVP). Conduction system pacing (CSP) with HBP or LBBAP have been associated with reduction in death or heart failure hospitalization (HFH).

MAT is not a Wandering Pacemaker. In contrast — a wandering pacemaker is often a benign rhythm ( if not a normal variant ) — in which the heart rate is slower and there is a gradual shift in P wave morphology over a period of several beats, most often occurring in an otherwise healthy and asymptomatic patient.
