Why the study?
What is the long-term survival and what are the prognostic factors in patients receiving pacemakers compared to the general population?

Comparison
Pacemaker implantation (96.2% VVI) vs Matched general population of Yugoslavia

Follow-up

Observed survival advantage in elderly male pacemaker patients warrants caution; leaves open selection bias in this Level 3 cohort.
What is the long-term survival and what are the prognostic factors in patients receiving pacemakers compared to the general population?
Pacemaker patients, particularly those without underlying structural heart disease, have excellent short- and long-term survival that is comparable to or better than the general population.
