Ten patients of the authors' practice who have survived to be 100 years of age or more have had an implanted pacemaker for an average of 11.4 years. As the life expectancy of the country (Uruguay) is 75 years, their survival is considered to be unusual, confirming the statistical conclusion that patient survival with an implanted pacemaker may be expected to be as good or better than those who do not require a pacemaker implant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
