Syncope—also called fainting, or passing out—is a sudden loss of consciousness. It can happen due to changes in the nervous system and the circulatory system and is a result of a temporary drop in the amount of blood and oxygen reaching the brain.

Heart palpitations feel like extra strong heartbeats or a fluttering in your chest. Rapid heart beat can cause your blood pressure to drop, which may lead to fainting. You may also experience heart palpitations if your blood sugar is too low, which can be dangerous. This is more common among people with diabetes who take medicine to increase hormone levels in the body.
