Auxiliary examination _'s symptom of the viral myocarditis
(1) Check in the laboratory1.Check leucocyte between the the intersection of total number and 1- 2 Wan generally, neutral grains of on the high side cell. Accumulate and sink, resist " O " The great majority are normal.2.Serum enzyme is determined Creatine phosphokinase (CPK) , enzyme lactic dehydrogenase (LDH) And isoenzyme (MB) , millet straw transaminase (COT) It is early in the course of disease can increase. Exceed and oxidize fork enzyme (SOD) Acute one is reduced.3.Virus separate from pericardium and cardiac muscle, or membrane separate, to virus, check, find in the cardiac muscle having peculiar virus antigen with the intersection of immunity and fluorogenic antibody in the heart, the electric mirror checks the cardiac muscle to find that there are virus particles, can fix and diagnose; Swallow and isolate the virus in the lotion, excrement and urine, blood, pericardium liquid, combine and neutralize antibodies and drip degree rising with the virus or dropping more than 4 times more than serum of the first in convalescent serum at the same time, help the etiology to diagnose.4.Determine and the nuclear acid measuring thing different charges in nature antibody of virus with antibody, the complement combines the determination of the antibody and hybridizes law or polymerase chain and reacts (PCR) with the molecule The virus core found in myocardium cells sour to help the etiology to diagnose too. Some viral myocarditis patients can resist the myocardium antibody to present, generally resume in a short time, if improve continuously, show pathological change of myocarditis is in activity one. (2) Check in electrocardiogramThe acute one of electrocardiogram has changeable and variable things to click, should check the suspicious case repeatedly, in order to help and diagnose. It mainly varies to ST-T and changes, disorder of various rhythms of the heart and block:1. The change section ST of section ST-T and QRS wave drops (pericardium can see and raise while accumulating the liquid) ,T wave is low and flat, two-way or inverts. There can be low-voltage, one is lengthened among Q-T. Large stretch of myocardium necrosis and occasionally spacious Q wave, similar myocardium infarction.2.Rhythm of the heart is disorderly except that sinus tachycardia, sinus are aroused in interest and too slow, it is obvious various are fought early (room, room, forming) Among them fight to see more early with the room. Sex or room tachycardia, atrium are fluttered or quivered on the room, it can be seen that the room is quiver.3.It is rather common to conduct the overcast stagnat sinus room, room room or indoor block, among them see at most with I-II one degree of atrio-ventricular block.Fighting early by all kinds of, in order to see more in convalescence. Minority whether chronic issue can have the intersection of room and the intersection of room and plump change while being getting ill. (3) X-ray examinationThe increase of the heart with normal or at various degrees shadow, the majority, in order to increase slightly. If it is in heart failure to delay and does not heal or amalgamate repeatedly, cardiac dilatation is obvious. The latter can be seen the heart and beat and weaken, companion's lung extravasated blood, lung edema or thorax accumulate the liquid on a small quantity. When there is pericarditis, accumulate the liquid to solicit. (4) Cardiac muscle of membrane live and examine (EMB) in the heartHeart the intersection of conduit and law the intersection of membrane and cardiac muscle live, examine, already launch in the patient in adult in the heart, child's patient has reports in recent years, have offered the pathological basis for the fact that myocarditis is diagnosed. It is reported that: Not normal, congestive patient in heart failure of rhythm of the heart with unidentified reason, is proved about 40% are the myocarditis by EMB; Clinical manifestation and histologic relevance are relatively bad. The reason is a very small and limitation that EMB draws materials, and might not be the best chance while drawing materials; EMB can cause myocardium cells to shrink, and present some pathology false marks. Examine pathology, have person who displays myocarditis might not represent to EMB heart there is not myocarditis while being living, the clinician can't ignore clinical diagnosis at this moment. This examines it is launched, does not do as the routine inspection project that the too far away to be readily accessible general hospital is still too difficult.
