What're the symptoms of fainting?
Fainting (syncope) is a sudden, temporary loss of consciousness due to insufficient oxygen supply to the brain. The most frequent signs and symptoms are sudden lightheadedness, generalized weakness, and then falling. These signs and symptoms can be accompanied by blurred vision, nausea, paleness, sweating, rapid heartbeat and rapid breathing. If
heartbeat or breathing is not present, this may represent cardiac arrest rather than fainting. The symptoms that a patient may feel before fainting are heart palpitations that is feeling or hearing the heart beating very fast, nausea or a feeling of vomiting or dizziness, weakness, palpitation and a black out.
The patient looses consciousness generally following symptoms of dizziness, light headedness, alterations in or loss of vision and sometimes extreme ringing in the ears or loss of hearing. Loss of muscle control will cause the patient to fall to the ground or slump if seated. There may be other symptoms such as an irregular or rapid heart rhythm (arrhythmia), sweating and nausea. Jerks and spasms may occur, these may look similar to an epileptic seizure but these movements are not associated with epilepsy.
