Syncope is a condition in which a child loses consciousness for a short period of time

It occurs suddenly in older children and adolescents aged 8-18 years. Symptoms usually occur suddenly, causing shock to both the child and the parents. Usually, this symptom is caused by lack of oxygen to the brain. It is a serious risk factor, making diagnosis and management of this disease very important. A detailed history and physical examination are required to differentiate syncope from seizure, which is often accompanied by twitching and permanent brain abnormalities.

Observe the symptoms of a child fainting:

1. Dizziness
2. Cold body, sweating
3. See a blurry image
4. Exhausted, no energy
5. Nausea, vomiting
6. Unconsciousness (in some cases)

The main causes of fainting are divided into two groups:

1. Common fainting

It is the most common cause of fainting, usually found in teenagers and females. It is caused by an imbalance of the nervous system and blood vessels (Neurocardiogenic syncope). Conditions that cause certain abnormalities in blood vessels, such as standing for a long time until blood pools in the legs, being unwell, dehydration, or being excited or shocked, cause the blood vessels to return less blood to the heart. The heart contracts more คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย slowly and not enough to nourish the brain. The child then faints and loses consciousness for a moment. Then the body’s self-defense system will work. The nervous system will order the heart to contract harder to provide enough blood to the brain. The child will recover normally.

Fainting in this group is considered not serious, not dangerous, and does not permanently affect the brain (benign). Simply observing and avoiding factors that trigger the symptoms will help improve the symptoms. However, if the symptoms occur frequently, the doctor may consider using medication to help balance the body’s functions in order to reduce the frequency and severity.

2. Fainting caused by heart disease or cardiac syncope 

is found much less frequently and may be a sign of a problem in the heart system. Symptoms usually occur during exertion or exercise. Although it is found less frequently than normal fainting, it is considered an abnormality that may cause serious consequences. You should receive prompt examination and treatment. Fainting caused by heart disease usually comes from:

• Abnormal electrocardiogram, irregular heartbeat, slow heartbeat or faster heartbeat than normal (tachy/bradyarrhythmia) all cause the heart to contract less, unable to send enough blood to the brain. Children can also faint and lose consciousness. Some may have symptoms of palpitations and chest pain as preceding signs. In this group, it is often inherited, so there is a family history of heart disease. Diagnosis is made by examining the electrical currents produced by the heart muscle during contraction (Electrocardiogram; ECG/EKG), which is an easy test that does not take long, is painless, and can screen out serious and dangerous abnormalities.
• Abnormal heart muscle or structure, stenosis of the heart valves, leaky heart valves, and thick or thin heart muscle cause the heart to work less efficiently and is insufficient for the body’s functions. In this group, patients may tire more easily than usual, play less than children of the same age, gain weight slowly, and have a heart murmur on physical examination.
• Abnormal blood supply to the heart, a group of congenital abnormalities of the coronary arteries, such as pulmonary hypertension, or a group that occurs later causing coronary aneurysms, such as Kawasaki disease.
