Significance of Asymptomatic Bradycardia for Subsequent Pacemaker Implantation and Mortality in Patients >60 Years of Age
Sinus bradycardia may be more significant in older patients than in a younger group because it could signal important or advanced conduction system and/or cardiac disease potentially modifiable with pacemaker implantation. We evaluated the clinical need for subsequent pacemaker implantation and mortality rate in outpatients >60 years of age with relatively asymptomatic bradycardia (heart rate [1] 0.130), whereas multivariable analysis showed protection (hazard ratio 0.78, 95% confidence interval 0.65 to 0.94, p [1] 0.010). In conclusion, older patients with asymptomatic bradycardia have a very low rate of pacemaker implantation, annualized to
