title: [Syncope in the elderly].
abstract: Age-related physiologic changes, a higher prevalence of chronic illness, and concomitant (often multiple) medication account for a higher susceptibility of elderly patients to syncope. Although elderly patients are the largest group with syncope, the causes frequently remain unclear. Multifactorial causes, lack of witnesses, overlap with falls, and additional cognitive impairment often confound the assessment of syncope in the elderly. Thus, strategic investigation is often needed to establish the diagnosis and to unmask the cause. In addition to a comprehensive medical history (by both patient and witnesses), a thorough physical examination including supine and standing blood pressure measurements and a standard 12 lead ECG remain the mainstay of diagnosis. The decision whether additional tests are needed depends on indications whether organic heart disease is present or not. Without evidence of structural heart disease, tilt table testing and studies of autonomic function are the next steps. In contrast, additional cardiac investigation (including invasive studies) is needed in patients with suspected or documented cardiac disease. External or implantable loop recorders represent a significant improvement in the diagnosis of rare episodes of (brady- or tachy)-arrhythmias. Prognosis is determined by the underlying (heart) disease.
