几乎任何病毒感染均能成为心肌炎的潜在原因,包括柯萨奇、ECHO、麻疹、风疹、腮腺炎、传染性单核细胞增多症、病毒性肝炎、流行性感胃、脑-心肌炎等病毒、腺病毒和肺炎支原体……等等。然而,主要的是柯萨奇病毒和ECHO病毒。柯萨奇病毒分A和B两型,B型产生心肌炎的毒力比A型强,是人体病毒性心肌炎的最常见原因。病毒性心肌炎的临床表现变异很大,从没有任何症状直至突然死亡,其心电图表现为S-T段抬高、T波低平或倒置、Q-T时间延长、暂时性异常Q波、室性心律失常和传导障碍。这些改变均非特异性。只有在发病的起初几天才能从喉拭、粪便、血液中分离到病毒,但此时心脏症状每被病毒感染症状所掩 Almost any viral infection can become a potential cause of myocarditis, including Coxsackie, ECHO, measles, rubella, mumps, infectious mononucleosis, viral hepatitis, epidemic stomach, brain - myocarditis and other viruses, adenovirus Mycoplasma pneumoniae ... and so on. However, the main Coxsackie virus and ECHO virus. Coxsackievirus A and B two sub-type, B-type myocarditis produces more virulence than A-type, is the most common cause of viral myocarditis in the human body. The clinical manifestations of viral myocarditis vary greatly, from no symptoms until sudden death, the ECG showed ST elevation, T wave low or inversion, QT prolongation, temporary abnormal Q wave, ventricular arrhythmia and conduction obstacle. None of these changes are specific. Only in the first few days of onset can be separated from the throat swab, feces, blood, the virus, but at this time each heart symptoms were covered by the virus infection symptoms
