Abstract

Cardiac conduction disturbance necessitating pacemaker implantation is common among elderly patients. However, patients often have comorbidities and increased frailty which may result in limited life prognosis and a high rate of procedure-related complications. We evaluated pacemaker implantation in older patients by comparing life prognosis and complication rate in patients aged ≥ and < 85 years. We retrospectively enrolled 262 consecutive patients who underwent initial pacemaker implantation for bradycardia (age, 77 ± 10 years old; male, 132 (50%); dual chamber pacemaker, 222 (85%) patients). Acute and long-term outcomes were compared between patients aged ≥ 85 and < 85 years. Primary outcome was a composite of all-cause death and severe procedure-related complications. Seven (14%) patients aged ≥ 85 years (n = 50; 19%) were non-ambulatory. During 2-year follow-up, primary outcome (death or severe complication) occurred in 47 (18%). Freedom from primary outcome was similar between age groups (81.6% versus 80.8%; p = 0.98). Freedom from all-cause death and from severe complication in the study period were also similar (all-cause death, 91.6% versus 88.7%, p = 0.70; severe complication, 89.7% versus 91.5%, p = 0.75).

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
