Excerpt

Presyncope, or near-syncope, is often poorly defined and may have different meanings to different healthcare providers, but it denotes a state of near-fainting or a prodrome of syncope. The most uniform definition is “feeling like one was going to pass out but without actual loss of consciousness.” Near syncope can last for seconds to minutes. A feeling of lightheadedness, general weakness, warmth, diaphoresis, nausea, palpitations, or blurry vision may accompany symptoms. Although often perceived as less severe than syncope, data suggest that the pathophysiology (cerebral hypoperfusion) and outcomes of near syncope mimic those of syncope.
