Complications of pacemakers and defibrillators in the elderly.
Within the United States, the elderly population is projected to increase 126% by 2050, making those over the age of 65 the most rapidly growing segment in the population. Permanent pacemakers and defibrillators are important therapies with expanding indications for their use, and older persons constitute the majority of recipients of these devices. Recognizing complications associated with these cardiac devices is essential in caring for patients with them. Complications can be related to the implantation procedure and are most commonly lead dislodgement, pneumothorax, lead perforation, hematoma, and infection. Intrinsic device programming can also result in complications such as pacemaker syndrome, pacemaker-mediated tachycardia, and inappropriate shocks. Extrinsic factors, such as electromagnetic interference and physically manipulating the device, can also result in problems. Recent work suggests that older age, by itself, is not associated with a significant increase in the complication rates from these devices and should not preclude their use.
