The basis of syncopal symptoms should be sought through careful evaluation. Only after a cause is established can an effective treatment regimen be developed. * * * This slide provides a simple classification of the principal causes of loss of consciousness. This scheme lists the causes of syncope from the most commonly observed (Left) to the least common (Right). This ranking may be helpful in thinking about the strategy for evaluating syncope in individual patients. Within the boxes,the most common causes of syncope are indicated for each of the major diagnostic groups. The numbers at the bottom of each column provide an approximate value for the average frequency with which that category appears in published report summarizing diagnostic findings (Alboni J Am Coll Cardiol 2001; 37: 1921-1928). It should be noted that orthostatic causes are not often referred to specialists and consequently tend to be under represented in the literature. Simlarly, non-syncopal attacks (e.g. epilepsy, TIA, somatisation disorders) are generally not referred to syncope clinic as they are easily diagnosed and differentiated from syncope during the initial evaluation. The percentage reported in this slide thus represent those cases misdiagnosed as syncope at the initial evaluation. * * Syncope is often confused with other apparent loss of consciousness diagnoses. It is crucial to consider this distinction first, prior to embarking on a diagnostic evaluation. * General rules for initiating the diagnostic evaluation of the syncope patient. The history must include detailed summary of events leading up to and following syncope events. Additionally, it is important to ascertain whether there is any evidence of underlying structural heart disease. The direction of subsequent evaluation
