"Possible causes/experiencing fainting"

In general-only here, causes of fainting/passing out/syncope include vasovagal (the most common cause), cardiac (**includes specific irregular heartbeat, typically duration-dependent), circulatory, neurologic, metabolic and drug-induced. Sometimes, there is no known cause (idiopathic), no identifiable cause.

**As applicable, for simplcity, using a Holter monitor, event recorder, or at the extreme, an insertable cardiac monitor (ICM), can sometimes confirm or rule out an irregular heartbeat (arrhythmia) as a particular cause.
