OBJECTIVE: To determine the diagnostic yield of investigations in patients presenting to the emergency department (ED) with syncope. To determine the cause of the syncope. PATIENTS AND METHODS: We retrospectively identified consecutive patients presenting to the ED who underwent investigations for syncope at a 1900 bed university teaching hospital during 4 months. From the medical records we abstracted clinical information, results of testing and the cause of syncope. RESULTS: A total of 117 patients participated in the study. The mean age was 57 year (range 6-93 year), and 45% were male. Diagnostic procedures most often performed were blood analysis, ECG, chest X-ray and Holter monitoring (respectively in 94.1%, 88.8%, 74.4% and 36,8% of the patients). The corresponding diagnostic yield for these test was 4.5%, 6.7%, 0% and 16.3%. Other procedures were (% of patients; diagnostic yield): Ct scan of the head (35.1%; 0%), transthoracic echocardiogram (24.8%; 6.9%), ECG monitoring (24.8%; 27.6%), EEG (19.7%; 0%), neurovascular imaging (19.7%; 0%), abdominal ultrasound (11.1%; 0%), Ct scan of the chest (11.1%; 23.1%), head up tilt test (7.7%; 11.1%), carotid sinus massage (3.4%; 0%), pulmonary ventilation perfusion scintigraphy (2.6%; 33%) and exercise test (1.7%; 0%). The most common cause of syncope was neurocardiogenic (58,5% of patients), followed by orthostatic (11.1%), cardiac (11.1%), unknown (9.3%), hyperventilation (3.4%), pulmonary embolism (2.5%), drug related (2.5%) and others (1.7%). CONCLUSION: Patients admitted in the ED for syncope undergo various investigations. However, the diagnostic yield is poor.The most common cause of syncope is neurocardiogenic, followed by orthostatic and cardiac.
