What causes myocarditis in children? Are there any serious consequences?

Children's myocarditis is generally caused by colds, children do not pay attention to timely nutrition and body temperature cooling after a cold, the drug leads to the aggravation of the condition, if the resistance is poor, it will lead to the invasion of the virus, infection to myocarditis. Myocarditis can be severe, leading to serious complications such as heart failure, difficulty breathing, and heart failure.

Myocarditis is a disease that occurs more often in the green age, but some children can also get myocarditis. The first manifestation of myocarditis in children is early on. This manifestation is usually not easy to detect, and some children are only found after an electrocardiogram (ECG), which confirms the disease of myocarditis.

The second harm of myocarditis in children is that it can cause damage to the conduction system of the child's heart, so that the excitement of the child's heart cannot be transmitted to different parts of the heart normally. Patients with mild symptoms will not have any symptoms, and if the condition is more severe, they may have convulsions all over the body or even sudden cardiac arrest.

What are the symptoms and dangers of myocarditis in children? Myocarditis is mainly caused by various infections, poisoning, invasion of myocardium by hoof tissue tissue, and the most common is viral myocarditis. Viral myocarditis can cause myocardial inflammation in the heart muscle, and some can be accompanied by pericardium or endocarditis.

Depending on the age of onset and the acute and chronic course of infection, the prognosis is generally good, and a few can develop heart failure, cardiogenic shock and even sudden death. Children with mild symptoms generally have no self-conscious symptoms, which can be manifested by abnormal electrocardiogram, and when myocardial involvement is obvious, symptoms such as precordial muscle discomfort, chest tightness, shortness of breath, dizziness, and fatigue may occur. Mild cardiac enlargement with tachycardia, muffled heart sounds, and galloping rhythm can lead to heart failure and fainting.

Children with recurrent heart failure are prone to significant heart enlargement complicated by severe heart rhythm disorders, and severe children can suddenly develop cardiogenic shock and die in a short period of time. Some children are mainly examined with bad complexion or blue around the mouth, so it is necessary to detect myocarditis in time and diagnose it early.

Myocarditis is a very serious disease, in the early stage of the disease, patients will have high fever, loss of appetite, malaise and other adverse symptoms, with the aggravation of the disease, it will also cause arrhythmia and heart failure, which will have a great impact on the baby's health and health growth. So what causes myocarditis in children?

First of all, it may be caused by a viral infection, when the virus enters the child's body, it will reach the heart of the human body with blood circulation, which may directly damage the child's heart cells, which will induce the production of myocarditis in the baby. Some children have a virus** infection, which will lead to low immunity in the body, resulting in serious damage to heart cells.

It may also be caused by bacterial infection, when the child's body immunity is low or there is a phenomenon of bacterial infection, it will also cause myocarditis, in the early stage of the onset of the child will have symptoms of high fever and weakness of limbs, as the condition becomes more serious, it will also cause other complications, so it should be checked in time and rational use of drugs to avoid more serious infections caused by myocarditis in the baby.

Babies with myocarditis may also experience symptoms such as shortness of breath, fatigue and chest pain, and as the disease becomes more severe, it can also cause arrhythmias, heart failure, and cardiogenic shock. Therefore, if the baby has myocarditis, he should go to the hospital in time to avoid missing the best time to cause more serious complications.

Pediatric myocarditis is a common heart disease in children, and if it is not carried out in time**, the child may be life-threatening, and it is relatively easy to develop in the early stage**. When a child suffers from myocarditis, there will be a lot of symptoms of chopping. So, what are the early symptoms of myocarditis in children?

In the early stages of myocarditis, children generally have symptoms such as loss of appetite, irritability, nausea and vomiting, and the child's activity level is significantly reduced, and the mental state is not good. Older children may report to their parents that they feel chest tightness, palpitation, and dizziness and weakness. If you observe your child's heart rate, you will find symptoms such as tachycardia, irregular heartbeat, and frequent premature contractions.

Generally, the symptoms of pediatric myocarditis at the beginning of the disease are very similar to a cold, there will be sore throat, fever, runny nose and cough, etc., which is easy for parents to mistake their children for a cold, thus delaying the first time. After the disease progresses, the above symptoms will slowly improve and disappear, but then Gao Kaichang will have abnormal heart symptoms.

When some children first suffer from myocarditis, they will suddenly have cardiogenic shock, or even cardiac insufficiency, severe heart rhythm disorders and other symptoms, which is called fulminant myocarditis, and its symptoms are irritability, paleness, cold limbs, and will be accompanied by cyanosis of the toes and fingers, weak pulse and blood pressure drops, and sometimes the child will have convulsions, coma and other conditions.

Analysis: Symptoms of myocarditis in children.

1.The oxygen supply to the human body is insufficient, the face is pale or blue-purple, **chills, chest tightness, and difficulty breathing. 2.

Blood circulation is blocked, the heart is enlarged and the liver is enlarged. 3.Myocardial insufficiency, which is characterized by a rapid heartbeat and a weakened pulse, arrhythmias, and a drop in blood pressure.

Suggestions:

Congenital cause, and there is also a fever that affects the heart.

Clinical manifestations of pediatric myocarditis.

The severity of the disease can range from acute heart failure and arrhythmia to acute heart failure and arrhythmia, and mild cases with insignificant symptoms until the chronic phase of dilated cardiomyopathy is found.

1.Acute phase.

The disease is new, the clinical symptoms are obvious and changeable, and the course of the disease is usually not more than 6 months. Mild symptoms, mainly fatigue, followed by excessive sweating, pallor, palpitations, shortness of breath, chest tightness, dizziness, lack of energy, etc. On examination, there may be pallor, perioral cyanosis, a dull first heart sound at the apex, a gentle wind-like systolic murmur, and sometimes premature contractions.

Medium-sized is less. The onset is acute, and in addition to the above symptoms, fatigue is prominent, and older children often complain of precordial pain. Patients with acute onset may be accompanied by nausea and vomiting.

On examination, the heart rate is too fast or slow, or the heart rhythm is irregular. The child may be irritable, cyanotic around the mouth, cold hands and feet, and cold sweats. The heart may be slightly enlarged, with dull heart sounds, a wind-like contraction murmur at the apex, galloping rhythm, and/or various arrhythmias.

Low blood pressure, low pulse pressure gradient, enlarged liver, and rales in some lungs. Severe and rare, fulminant, abrupt onset, cardiac insufficiency or sudden cardiogenic shock within 2 days. The child is extremely fatigued, dizzy, irritable, vomiting, and precordial pain or pressure.

Some have difficulty breathing, sweating profusely, and are clammy and cold. Small babies refuse to eat, are fussy, weak, cold hands and feet, and have difficulty breathing. On examination, the body is pale, cyanotic lips, cold extremities, cyanosis of the fingers and toes, weak or unpalpable pulse, and low or undetectable blood pressure.

Heart sounds are dull, the first heart sound at the apex is barely audible, systolic murmurs may be present, and gallop rhythm, tachycardia, bradycardia, or severe arrhythmias are common. There are rales in the lungs, and the liver can be rapidly enlarged. Some develop acute left heart failure and pulmonary edema.

The disease progresses rapidly, and if the rescue is not timely, it is life-threatening.

2.Postponement of relocation.

After the acute phase, clinical symptoms recur, ECG and x-ray changes persist in healing, and laboratory tests show signs of disease activity. The course of the disease is usually more than 6 months.

3.Chronic phase.

Progressive heart enlargement, or recurrent heart failure, with a duration of more than 1 year. The chronic phase is more common in children, and some have an insidious onset and are chronic when found; Some of them are not resting enough in the acute phase or are not timely and repeated many times, resulting in the chronic phase. It is often delayed for several years and results in death from infection, arrhythmias, or heart failure.

Experts from Wotianwang reminded that the prevention of acute myocarditis lies in avoiding the first element, and in case of severe heart failure or shock, it should be sent to the hospital for treatment immediately.

The clinical characteristics are that the severity of the disease is very different, the conscious symptoms are milder than those found in the examination, and most of them have a history of upper respiratory tract infection or digestive tract infection and other diseases and viruses within 2 or 3 weeks before the onset of cardiac symptoms.

1.Acute phase.

New onset, clinical symptoms are obvious and changeable, the course of the disease is not more than 6 months, mild symptoms, mainly fatigue, followed by excessive sweating, pallor, palpitations, shortness of breath, chest tightness, dizziness, lack of energy, etc., examination can see pale, there may be cyanosis around the mouth without jujubes, the first heart sound at the apex is low and dull, a gentle blow-like systolic murmur can be seen, sometimes there is a premature contraction, less medium, the onset is more acute, in addition to the above symptoms, the fatigue is prominent, older children often complain of pain in the precordial area, and those with a more acute onset may be accompanied by nausea and vomiting, Examination shows rapid or slow heart rate, or irregular heartbeat, the child is irritable, cyanosis may appear around the mouth, cold hands and feet, cold sweat, heart may be slightly larger, dull heart sounds, wind-like contraction murmur at the apex, galloping rhythm and/or various arrhythmias, low blood pressure, low pulse pressure difference, liver enlargement, some lungs have rales, severe and rare, fulminant, rapid onset, cardiac insufficiency or sudden cardiogenic shock within 1 or 2 days, extreme fatigue, dizziness, irritability, vomiting, pain or pressure in the precordial area, and some dyspnea, Sweating profusely, ** clammy and cold, small babies refuse to eat, bursts of fussiness, weakness, cold hands and feet, difficulty breathing, gray and pale color on examination, cyanosis of the lips, cold limbs, cyanosis of the fingers, weak pulse or can not be touched, low or undetectable blood pressure, dull heart sounds, the first heart sound at the apex of the heart can hardly be heard, systolic murmurs may appear, often galloping rhythm, tachycardia, bradyarrhythmia or severe arrhythmia, rales in the lungs, the liver can enlarge rapidly, and some occur acute left heart force rock car failure, pulmonary edema, the disease develops rapidly, such as rescue is not timely, There is a danger to life.

2.Postponement of relocation.

After the acute phase, clinical symptoms recur, ECG and X-ray changes are prolonged, laboratory tests show signs of disease activity, and the course of the disease is more than half a year.

3.Chronic phase.

Progressive heart enlargement, or recurrent heart failure, the course of the disease is more than 1 year, the chronic phase is more common in children, some have an insidious onset, and are chronic when found; Some are not resting enough in the acute phase or ** are not timely and repeated many times, resulting in a chronic phase, often delaying for several years and dying of infection, arrhythmia or heart failure.

Cardiomyopathy is a type of myocardial disease of unknown origin, and it does not include starvation-specific cardiomyopathy that is definitive or secondary to systemic diseaseCardiomyopathy can be divided into three types: dilated cardiomyopathy, hypertrophic cardiomyopathy and restrictive cardiomyopathy.
