A significant proportion of single-chamber ventricular pacemakers are implanted in octogenarian and nonagenarian patients. We aimed to assess whether the current pacing guideline is adhered for these populations.We retrospectively identified patients ≥80 years of age, who received their first pacemaker from July 2010 to June 2013.A total of 356 patients were identified. Mean age was 86.1 years and 82.6 years for single and dual-chamber pacemakers respectively (p0.05). Total procedure-related complications occurred in 9.5% and were comparable between both groups (p=0.08). At the time of implantation, 185 patients who received single-chamber pacemaker were in sinus rhythm (52%). They were older (86.2±4.3 vs 82.6±2.9, p0.05), more likely to have ischaemic and valvular heart disease (68 vs 27, p= 0.02 and 22 vs 13, p=0.01, respectively), and cognitive impairment (34 vs 0, p= 0.001). They were also more likely to be discharged to a residential care facility (17 vs 1, p0.01).The utility of dual-chamber pacemaker in this age group remains below expectation and did not comply with current cardiac pacing guidelines. The presence of older age, multiple co-morbidities, cognitive impairment and residential care on discharge likely influenced the type of device implanted. |
