All patients coming or brought to the emergency department were included. A total of 173 syncopes occured in 169 patients, (mean age 57 yrs) and 84 near syncopes in 83 patients, (mean age 58 yrs). The major causes were similar in both categories, and vasovagal attack the most common cause, in 30% of cases for syncope (mean age 39 yrs) and 37% for near syncope (mean age 46 yrs). The second most common cause were cardiovascular diseases, in 26% of cases with syncope considerably higher than most of previously published studies have shown. Cardiovascular diseases caused near syncope in 28% of cases. In 14% of cases, drugs caused the syncope and in 17% with near syncope. A significant number of patients with an iatrogenic occurence. In the syncope group 10% of the patients had an unknown cause, a lower percentage than in similar, previously published studies. The most important factor in revealing the diagnosis was a thorough history and examination, which gave the diagnosis in over half of cases. Continuous heart monitoring (48 hour Holter monitoring) was the second most helpful tool in arriving at the diagnosis, and an EKG also proved to be helpful in both groups of patients. An invasive electrophysiologic study was performed in 11 selected cases and lead to the diagnosis in 7 patients. This study demonstrates the importance of near syncope, since 28% of patients with this symptom have a serious disorder. The etiologies of syncope and near syncope are similar and should be investigated and treated in the same way. Aðsvif er algengt fyrirbæri sem mikið hefur verið rannsakað.
