It is commonly described as \u201cnear-fainting,\u201d lightheadedness, or a sensation of \u201cblacking out\u201d without actually passing out. Clinicians use the term Presyncope in cardiology and general medicine because it can reflect temporary reduced blood flow to the brain. It often appears in symptom checklists, emergency assessments, and outpatient cardiovascular evaluations."}
