重型急性心肌炎的诊断常不困难,因为临床上常有显著的心脏扩大以及进行性心力衰竭,但临床上具有这种感染性心肌炎的过程是罕见的;相反,轻型的临床上缺乏症状的心肌炎则很常见。由于轻型急性心肌炎(AMM)病人可能会突然发生心源性死亡或隐匿地发展为充血性心肌病,因此有必要对这些病人作出正确诊断。鉴于 AMM 的诊断界限很不明确,为此作者对185例在军队中服役的、由于急性感染性疾病具有ECG 变化而怀疑有心肌炎的年青人进行了研究。其中160例根据 ECG 变化可分为心肌心包炎、心肌炎、可能心肌炎、新近出现的室性期外收缩(VE)、短期
Diagnosis of severe acute myocarditis is often not difficult because clinically significant enlargement of the heart and progressive heart failure, but the process of having such infectious myocarditis clinically rare; on the contrary, the lack of clinical clinical symptoms of myocarditis very common. Since patients with AMM may have sudden cardiac death or develop an occult cardiomyopathy, it is necessary to make a correct diagnosis of these patients. Given the ambiguous diagnostic boundaries of AMM, the authors studied 185 young men suspected of having myocarditis who served in the military and had ECG changes due to acute infectious disease. 160 of them according to ECG changes can be divided into myocardial pericarditis, myocarditis, possible myocarditis, the recent occurrence of ventricular contraction (VE), short-term
