Pain in the chest

If you get chest pain it can have many different causes. One of the most common is that the muscles in the chest hurt because you strained them more than usual. Mental stress can also create a feeling of pain or discomfort in the chest. Occasionally, chest pain may be due to diseases of the heart, stomach or muscles. A strong, pressing pain in the chest can be symptoms of angina or heart attack and then it is important to seek care.

Swollen lymph nodes

It is common for children and adults to have swollen lymph nodes. Then they are often tender and bigger than they usually are. For example, it may be due to a viral infection in a cold, a bacterial infection in the throat, or a wound that is infected. If you have swollen lymph glands larger than two centimeters, they should be examined by a doctor.


If you have a myocardial infarction, the double membrane that is around the heart has become inflamed. In rare cases, fluid may accumulate between the membranes. Then the heart becomes more difficult to pump the blood and the blood circulation becomes worse. With treatment, inflammation can go away quickly, but sometimes it takes months or years.

Infections of the heart in children

Children can have three different types of infections or inflammations of the heart. All three variants are unusual. The infections are caused by viruses or bacteria, which spread to the heart. It can happen when the child has an infection elsewhere in the body or during surgery. It can also occur without knowing the cause.


Heart palpitations in the form of extra beats, hard heartbeats or short-term heart murmurs are common and occur at all ages. Usually, there is nothing to worry about, especially if the trouble comes in connection with stress or worry. But if you get heartache and at the same time feel sick, get chest pain or difficulty breathing, you should seek treatment immediately.

Permanent atrial fibrillation

Atrial fibrillation means that the heart beats irregularly and often even faster. This means that the heart cannot pump around the blood in the body as efficiently as it usually does. Permanent atrial fibrillation is the most common cause of stroke. This is because the flicker degrades blood circulation in the atrium of the heart, making blood clots more easily formed.

Sudden cardiac arrest in athletic children and adolescents

Although it is very uncommon, sports children and adolescents may suddenly experience unexpected cardiac arrest. This is usually because the child has had some disease of the heart muscle or the duct system that you have not previously known about.
