Key result
US permanent pacemaker use rose ~56% from 1993 to 2009, dominated by dual-chamber devices.
Why the study?
Contemporary trends in permanent pacemaker use in the United States have not been well defined since the Medicare National Coverage Determination has remained unchanged since 1985.
Population
2.9 million patients receiving permanent pacemakers in the United States from 1993 to 2009
Comparison
Dual-chamber (DDD) vs single-chamber ventricular (VVI) vs single-atrial (AAI) vs biventricular (BiV) devices
Design
Observational analysis of the Nationwide Inpatient Sample database

Permanent pacemaker implantation in the US increased by 55.6% from 1993 to 2009, driven by a significant shift toward dual-chamber devices despite older and more comorbid patient populations.

Greenspon et al. (2012) conducted an observational in Permanent pacemaker implantation (n=2,900,000). Time period (2009 vs 1993) vs. 1993 was evaluated on Dual-chamber (DDD) pacemaker use (p=<0.001). Between 1993 and 2009, overall permanent pacemaker use in the US increased by 55.6%, with dual-chamber device use increasing from 62% to 82% (P<0.001) and single-ventricular use falling to 14%.
