This large study of long-term cardiac pacing for bradycardia in octogenarians and nonagenarians showed a cumulative 5-year survival of ~50%, which compares with that of age- and sex-matched controls. These data suggest a beneficial impact of bradycardia pacing, restoring life expectancy to previous levels. The occurrence of PM complications during long-term follow-up is not infrequent with 18.1% of patients experiencing a PM-related complication during a mean of 5.8 years follow-up. The complication rate was not higher than in younger PM patients.
