Pacemaker implantation's cognitive effects in elderly patients remain unclear; leaves open need for randomized confirmation before practice change.
Rockwood et al. (1992) conducted a case-control in Dysrhythmias. Pacemaker implantation vs. Matched volunteer controls without dysrhythmia or intervention was evaluated on Subjective and clinical impressions based on family interviews and results of psychological test battery. Pacemaker implantation did not alter cognitive functioning 6-12 months post-implantation in elderly patients with dysrhythmias, despite subjective impressions of improvement.
