Symptoms of myocarditis in children

summary

Myocarditis in children refers to the inflammatory lesions of myocardium caused by various reasons. Many factors, such as infection, physical and chemical factors, can cause myocarditis. The degree of myocardial damage caused by myocarditis is very different, and the clinical manifestations are different. Mild patients have no symptoms, while severe patients can have heart failure, cardiogenic shock and even sudden death. Most patients can be cured after treatment, and some patients develop dilated cardiomyopathy after acute phase, and heart failure can occur repeatedly. The symptom of infantile myocarditis tells everybody.

Symptoms of myocarditis in children

Premature beat is one of the manifestations of viral myocardium. Most of the children have no discomfort, ECG examination was confirmed. If the child is in good condition, the heart does not expand, and the heart function is normal, drug treatment can not be given for the time being. Premature beats will gradually reduce and disappear, but attention must be paid to the rest and nutrition of the child.

Heart block is a virus that damages the conduction system of the heart, so that the excitation of the heart can not be transmitted normally in different parts of the heart. Mild cases can be found only by ECG examination without any manifestation; In severe cases, the rhythm of heart beat became slow or irregular. If the heart rate per minute is less than 40 times, the child will have cerebral ischemia, causing convulsions, and even sudden cardiac arrest. This kind of critical myocarditis needs to be treated in hospital.

Heart failure is a manifestation of severe myocarditis. Children with heart enlargement, myocardial contractility decline, so that the heart can not effectively play the role of blood pump, so that the body tissue oxygen supply can not meet the normal needs. At this time, children can appear shortness of breath, pale, heart rate, weak pulse, can not lie on their back and other symptoms. If not sent to the hospital in time for treatment, it will endanger the lives of children.

matters needing attention

The diagnosis of myocarditis is generally made according to the characteristics of etiology, clinical symptoms and signs related to heart, abnormal ECG found in laboratory examination, increased markers of myocardial necrosis, abnormal echocardiography, and exclusion of other heart diseases. The exact diagnosis of myocarditis requires histopathological evidence, mainly the results of endomyocardial biopsy.
