title: Permanent cardiac pacing for brady-arrhythmia.
abstract: The indications for and technology associated with permanent cardiac pacing have undergone major changes during the past decade. In contrast to the 1970s, most patients now receive cardiac pacing devices subsequent to the diagnosis of sick sinus syndrome. However, since this condition is prevalent in elderly patients, it is crucial that indications for pacing be critically evaluated and pacing recommended only for those with documented symptoms or marked abnormalities indicative of high risk for a subsequent cardiac event. This is particularly important because pacing has not been shown to influence survival in these patients. The technological advances in pacing devices during the last ten years now provide many desirable options. As a result, available pacemakers range from very simple to highly complex; accordingly, they have a wide range of prices. It is more important than ever to carefully select the appropriate pacing device for a given patient, since its cost, longevity, and required follow-up may differ greatly.
