What symptom does ventricular septal defect child have?
summary
Ventricular septal defect (VSD) in children is a kind of congenital disease, which is also a common kind of heart disease. Patients can be diagnosed by color Doppler ultrasound and X-ray chest film. And the disease in patients will have obvious symptoms, patients with common sense of disease will find abnormalities, so what are the symptoms of children with ventricular septal defect disease? Now let's talk about it.
What symptom does ventricular septal defect child have?
the child is asymptomatic, and is usually found heart murmur by accident during physical examination. The child has normal growth and development, ruddy complexion, flexible response, no deformity of chest wall, normal size of left ventricle and no abnormality of peripheral blood vessel pulsation. The main signs are: there is a loud systolic murmur on the left lower edge of sternum, often accompanied by tremor, and the murmur is mostly full systolic; For small muscle defects, the murmur is characterized by a short and high pitched systolic murmur at the left lower edge of the sternum. Due to the narrowing or sealing of the holes between the muscle trabeculae during myocardial contraction, the murmur stops in the middle of contraction. The strength of the heart murmur is not directly related to the size of the ventricular septal defect.
children often have clinical manifestations when their pulmonary circulation resistance decreases 1-2 months after birth. Due to the large pulmonary circulation flow, pulmonary edema, increased pulmonary venous pressure, decreased lung compliance, sucking difficulty, fatigue during feeding, sweating, weight loss, and later height development delay, shortness of breath, repeated respiratory tract infection, further aggravating the formation of heart failure, Physical examination: the face of the child is ruddy, the reaction is slightly poor, the pulse rate increases quickly, and the strength is normal. However, when there is severe heart failure or a large left to right shunt, the pulse weakens, the child has dyspnea, shortness of breath, costal space invagination, and the precordial pulsation is obvious due to left ventricular hypervolemia.
in older children, obvious protrusion of precordial region and Harrison groove can be seen, palpation can be made, apex pulsation can be moved out, left ventricle can be lifted, systolic tremor can be often touched on the left lower sternum, the second heart sound is loud on auscultation, and typical total systolic murmur can be heard on the left lower sternum when pulmonary hypertension occurs, such as the type of subarterial defect, When there is a large left to right shunt, the third heart sound and mid diastolic rumble like murmur can be heard at the apex of the heart. In contrast, when children grow up to 6 months to 2 years old, the proportion of heart failure can be reduced.
matters needing attention
Ventricular septal defect in children can be divided into small defect and medium to large defect according to the type of disease. The symptoms are different, and the damage to patients will be different. Therefore, the baby should pay close attention to physical abnormalities after birth, regular child care examination, can find the disease of the body, but also can find children with ventricular septal defect disease.
