Metadata[+] Show full item record
The best diagnostic approach to a patient with dizziness is a limited physical examination and a directed history, followed by a targeted evaluation for vertigo, hearing loss, focal neurologic findings, orthostasis, or syncope whenever noted. (SOR A, based on a systematic review.) A blood glucose determination in all patients and an electrocardiogram (ECG) in patients older than 45 years have also been recommended. (SOR B, based on a cohort study.)
