摘　　要： 本文通过对临床诊断为心肌炎，放射性核素心肌灌注检查（ｓｉｎｇｌｅｐｈｏｔｏｎｅｍｉｓｓｉｏｎｃｏｍｐｕｔｅｄｔｏｍｏｇｒａｐｈｙＳＰＥＣＴ）阳性的５例患者，治疗前后进行心电图（ＥＣＧ）及高频心电图（ｈｉｇｈｆｒｅｑｕｅｎｃｙｅｌｅｃｔｒｏｃａｒｄｉｏｇｒａｍＨＦＥＣＧ）检查。结果显示：治疗前ＥＣＧ阴性，ＨＦＥＣＧ阳性，切迹数１４～２５个，治疗后ＥＣＧ阴性，ＨＦＥＣＧ阴性切迹数５～７。提示ＨＦＥＣＧ诊断心肌炎的敏感性高于ＥＣＧ，且可作为心肌炎动态变化的指标。Patients suffering from myocarditis were examined with ECG、SPECT and HFECG before and after treatment.All had positive SPECT results.Our results showed:HFECG was positive before treatment and the numbers of high frequency notching(HFN)were between 14～25.After treatment,the HFECG was negative and the numbers of HFN were 5～7.By contrast,the ECG was always negative.It is suggested:to diagnose myocarditis,the HFECG is superior to ECG and can be used as a mark of continuous change of myocarditis.
