Initiële diagnostische strategie bij wegrakingen: het belang van de anamnese

It is estimated that almost half of the people experience a transient loss of consciousness at some time during their life. In young patients ( <35 years) the cause is mostly a reflex syncope. In older patients the common causes are orthostatic and postprandial hypotension, sinus caroticus syndrome, cardiac arrhythmias and valvular disorders. The medical history can identify a probable cause of the transient loss of consciousness in almost all young patients ( <35 years) and in the majority of older patients. A physical examination and an ECG should be performed in all patients who have experienced a transient loss of consciousness, other than those with classical vasovagal syncope, in order to exclude orthostatic hypotension and dangerous cardiac causes
