Sudden death is mostly due to congenital deficiencies Sudden death in sports such as running, basketball, volleyball, soccer and other sports, and even in some low-intensity sports have also occurred sudden death, especially sudden death in sports, most of the young people in the body can not see the difference. Why do young “healthy people” have this problem? Chen Bojun said that the vast majority of young people who die suddenly have congenital heart disease. Usually there are no typical symptoms, and they are so hidden that most patients are unaware of them. For example, there is a kind of heart disease called “Bragada Syndrome” will be sudden malignant arrhythmia and death. This disease is usually asymptomatic, and even ultrasound and cardiac imaging can not detect the problem, only the electrocardiogram may be a little strange. In addition, there is a congenital disease called “Marfan’s syndrome”, with family characteristics, some patients have abnormal heart development, some cardiovascular development. For example, the American volleyball star Hyman, Russian skater Glinkov are suffering from Marfan’s syndrome. Symptoms during exercise should be taken seriously Exercise is a trigger for sudden death in patients with congenital heart disease. After exercise, a person’s heart beats faster, resulting in a shorter diastolic period, shorter blood flow into the coronary arteries, and coronary artery spasms may trigger sudden death. Even a few sudden deaths can occur without a cause, as seen in outpatient clinics where sudden deaths have occurred while talking on the phone on a daily basis. Sudden death is scary, but sports enthusiasts should not be alarmed. If there is a relative in the family who died prematurely, or if you have symptoms of chest tightness, you should pay attention to medical checkups. Such as electrocardiogram, cardiac ultrasound to see if there are congenital abnormalities. In addition, some patients may have a brief angina before the onset of the disease, or feel choking in the throat, swallowing something laborious, some people will be dizziness, panic, nausea, tightness in the chest, sweating, weakness and other symptoms appear, must pay attention to it, and according to the body’s needs, discontinue the exercise, rest.
