Syncope is a transient transient cerebral ischemia that causes the patient to faint. After syncope, the patient will exhibit symptoms such as dizziness, nausea, coma, and shock. Before syncope, the patient will experience weakness in the limbs and cannot support the body and faint. At this time, some patients will show two eyes up, foaming at the mouth, shortness of breath, and even some individual patients will show strange screams and other phenomena. Some patients can regain consciousness after a short rest and do not have any after-effects. However, some patients may experience incontinence and prolonged drowsiness after fainting. Such patients should be sent to the hospital for emergency treatment in a timely manner, where they should be treated with oxygen, investigation of the cause and, if necessary, blood pressure-raising drugs.
