general knowledge of viral myocarditis

general knowledge of viral myocarditis
It is caused that viral myocarditis the virus infringes the heart, regard myocarditis pathological change as disease mainly displayed, some can be with inflammation of membrane in the pericardium or heart.
Cause of disease
There are more than 20 kinds of to can cause virus of myocarditis: Ke Sa strange the virus ' Group A and group B) ,The but virus of angstrom, poliomyelitis and virus, the adenovirus, infective hepatitis virus, influenza, a influenza virus, measles and virus, simple sore rash and virus, mumps and virus, nose virus, and one kind of herpes viruses,etc.; Among them with strange the intersection of virus and group B Sa Ke ' 1-6 Type) The most common.
Symptom
Often have upper respiratory tract and intestinal virus that is infected with symptom, for instance in 1~3 weeks before the onset: Generate heat, cough, vomit, suffer from diarrhoea muscles and ache etc.. Symptom that the cardiac muscle is given much trouble is uncomfortable in the district before infant's main suit heart, palpitation, dizzy, abdominal pain and weak that chest uncomfortable in chest ached. Rhythm of the heart is disorderly in order to beat too early to see more, the lighter is right all without exception; The persons who send frequently often have palpitation, uncomfortable in chest; The disorder of serious rhythm of the heart can cause heart failure, faint, twitch. Serious the intersection of disease and patient can take place the intersection of heart and source shock, it displays to be extremely have the fidgets, the intersection of complexion and ashen, the intersection of skin and grow dim, the intersection of four limbs and clammy and end cyanosis.
[Note: Source shock of heart: It is the heart pump due to various causes of disease that outputs the function acutely and depletedly, whole body organ and organization can not get enough blood, thus produced a series of supersession and function obstacle syndrome.
Physical sign: Tachycardia appears under the quiet condition, being shown as individually is aroused in interest and too slow, arrhythmic. The heart circle of the person who amalgamates pericarditis obviously expand more. First low and pure sound, district of apex of the heart, part have the intersection of galloping horse and law, companion pericarditis person can hear, pass the intersection of and the intersection of pericardium and fricative. The critical patient displays pulse faintly, blood pressure drops; Two lungs present the rale; Liver splenomegaly, brief on circulatory failure. Electrocardiogram: The majority displays and lengthens as ST-T changing, one among Q-T, low-voltage, the sinus room, the room room or indoor block, beat too early, bunch prop up block, part can have paroxysmal tachycardia, atrium Piao move or quiver, even ventricle quivers. X The line is checked: The heart size expands the heartbeat to weaken normally and or lightly, intermediately, lung blood stasis or lung edema, can be seen a few thoraxes and accumulate the liquid sometimes.
Check in the laboratory: Early blood clear GOT, LDH, CPK, rising. And can separate the virus from swallowing department, excrement and urine, blood. Convalescent the intersection of serum and the intersection of virus and antibody drip degree, have more than 4 times raise than acute issue.
The supersound aroused in interest: The lighter has not changed, the heart of the heavy one is expanded, the wall and movement range of interventricular septum are lowered behind the left room, the cardiac pump function is reduced.
Dividing type: Clinical symptom and physical sign Electrocardiogram Course of disease and prognosis
It does not have obvious symptom that light, are not be in the mood for the function obstacle. Can be seen and beat too early or T unexpected turn of is reduced. The prognosis is good from several weeks to several months.
It has palpitation that medium-sized, uncomfortable, weak in the district before the heart,etc., the heart expanded companion's tachycardia slightly, the heart sound is low and pure, galloping horse's law. The electrocardiogram is obviously unusual The course of disease did not resume gradually from one year to several years
Get up disease to be many to appear acute the intersection of heart and depleted or heart source nature shock suddenly worried while being heavy-duty. If break out repeatedly the heart declines, then the heart is obviously expanded. Can erupt the serious disorder of rhythm of the heart or thromboembolism simultaneously. Can die within several hours or several days. Prognostic difference at a specified future date.
Treat
First, have a rest: It takes 3~4 weeks after acute one has a rest and retreats to heat at least. If the person who there are heart functionses complete and cardiac dilatation should put emphasis on absolutely staying in bed. No less than 3~6 months at generally total break, increase activity with conditions later.
Second, hormone: Generally used in heavier acute case, consumption goes on according to the doctor's order according to the condition.
Third, it is in heart failure to control: Because myocarditis is relatively sensitive to foreign digitalis preparation, apt to be poisoned, so the dosage should be partial and small. 1/2-1/3 that (effective dose can) . Serious disease can add diuretic and sedative.
Application of fourth, heavy dose of vitamin C and energy mixture.
Fifth, rescue source shock of heart.
Sixth, correct the arrhythmia, see the arrhythmia chapter.
Seventh, traditional Chinese medicine treatment.
Prognosis
Prognosis relate to weight of condition, if very serious get up disease, can receive prompt diagnosis, treat. And can guarantee enough rests, the general prognosis is better, the general prognosis of the serious case is relatively bad
