[Management of permanent pacemaker implantation in elderly patients].
We evaluated the clinical characteristics of 297 consecutive patients who underwent permanent pacemaker implantation. Their mean age was 67 +/- 13 years; those at least 75 years old accounted for 30.9%. The underlying diseases were sick sinus syndrome in 36.7%, atrioventricular block in 58.9%, and atrial fibrillation with bradycardia in 4.4%. There was no association between age and either the voltage threshold or the R wave amplitude at the time of implantation. When pacemakers were exchanged, only patients aged 75 years or less had voltage thresholds that were higher and lead resistances that were lower than those measured at the time of initial implantation. No clear differences were observed in the R wave amplitude, regardless of age. With careful long-term management, permanent pacemaker implantation and follow-up clinical care can be safe, even in aged patients.
