Symptoms of tetralogy of Fallot

summary

Many people do not know much about tetralogy of Fallot. Indeed, this disease is a common disease around children, and it is also a very common heart disease, which can lead to abnormal cardiac function. After the attack, many symptoms will appear. Let's look at the symptoms of tetralogy of Fallot.

Symptoms of tetralogy of Fallot

Cyanosis, cyanosis is the earliest appearance and is the main indication. Its severity and time are related to the narrow level of pulmonary artery. Cyanosis is more common in the parts with rich capillaries, such as lip, finger (toe) nail bed and bulbar conjunctiva.

Crouch, children walk every interval or game, like to squat for a long time. Due to the flexion of lower limbs during squatting, the amount of venous blood is reduced and the burden of the heart is relieved. At the same time, due to the compression of lower limb arteries, the resistance of systemic circulation is increased, which reduces the right to left shunt and temporarily relieves the symptoms of hypoxia.

Paroxysmal dyspnea or coma is easy to occur in infancy. Paroxysmal dyspnea often occurs during forced feeding or crying. Coma or convulsion occurs in severe cases (it is tied to the narrow base of the pulmonary artery infundibulum, where muscle spasm suddenly occurs, causing temporary pulmonary artery obstruction and aggravating hypoxia). Headache and dizziness can be complained of in older children.
