What are the symptoms of congenital heart disease

Congenital heart disease is also known as congenital heart disease. It is a disease caused by multiple factors during the fetal period. When the patient is in a mild state, there are no symptoms and it will only be discovered during a physical examination. Generally, symptoms of this disease will appear in infancy. As the age increases, the symptoms will become more serious, which will cause serious consequences for the patient.

Symptoms of congenital heart disease include:

1. Heart failure:

Chest tightness, precordial pain, and palpitations are more obvious, especially after activities. The children are pale, short of breath, have difficulty breathing and tachycardia. The heart rate can reach 160-190 beats per minute and the blood pressure is often low. You can hear the rhythm of galloping horses.

2. Cyanosis:

Purple coloration of the skin and mucous membranes can be seen at the tip of the nose, lips, nail beds, conjunctiva, etc.

3. Developmental delay and mental retardation:

When cyanosis appears, the child will have slow growth and development, low intelligence, and may have difficulty breathing when feeding or crying. In severe cases, the child may lose consciousness and have convulsions.

4. Clubbing and polycythemia:

Chronic hypoxia, metabolic disorders, and toxic injuries at the extremities. The soft tissue at the ends of fingers or toes proliferates, thickens, and becomes clubbed, and the nails are excessively curved in both vertical and horizontal dimensions like a parrot's beak. This is caused by chronic hypoxia.

5. Squatting:

When infants and young children are held, their legs do not straighten, but prefer to bend them on the adult's abdomen. When they sit, they like to lift their feet onto a stool, and when they stand, their lower limbs remain bent. When older children walk, they often feel a lack of oxygen to the brain, so they squat down with their knees close to their chest to rest for a while. This is medically known as the squat phenomenon.

6. Others:

Chest pain, syncope, sudden death. Some people have symptoms related to systemic circulation, such as abnormal sweating, which far exceeds the normal amount.
