Symptom: Syncope
Introduction: Syncope
Syncope means loss of consciousness such as fainting.
The term "dizziness" is often used for milder feelings
of lightheadedness that often precede a fainting episode.
The vague word "dizziness" needs to be distinguished from symptoms
such as balance difficulty, vertigo, fainting, or general weakness.
True dizziness is a lightheadedness or a sensation
that you are about to faint.
Any faintness or dizziness symptom needs prompt professional medical advice.

Article Excerpts about Syncope
Syncope is the
temporary loss of consciousness due to a sudden decline in blood flow to
the brain. It may be caused by an irregular cardiac rate or rhythm or by
changes of blood volume or distribution. Syncope can occur in otherwise
healthy people. The patient feels faint, dizzy, or lightheaded
(presyncope), or loses consciousness (syncope).
