Adjusted survival analysis showed that age \u2265 65, male sex, incremental increase in CCI, heart failure, prior year hospitalization, ED visit, and prior year pacing procedure were significant predictors of mortality. Age \u2265 65, male sex, and prior year hospitalization were significant predictors of a composite measure of device\u2010related complications.
