Allergic skin manifestations occurred in 48 patients, and 5 patients complained of shortness of breath. 56 patients (0.6%) felt dizzy during or immediately after the investigation. Nine patients complained of chest pain, three of whom developed myocardial infarction. Sixteen patients collapsed during the procedure. One healthy male, 42-year-old, collapsed after the injection of fluorescein during angiography, and electrocardiogram showed an asystole of 24 seconds.
