高频心电图在心肌炎诊治中的价值

THE VALUE OF HF-ECG FOR DIAGNOSIS AND TREATMENT TO MYOCARDITIS

本文观察了１８例急性病毒性心肌炎患者在应用黄芪治疗前后高频心电图（ｈｉｇｈｆｒｅｑｕｅｎｃｙｅｌｅｃｔｒｏｃａｒｄｉｏｇｒａｍＨＦＥＣＧ）中高频切迹（ｈｉｇｈｆｒｅｑｕｅｎｃｙｎｏｔｃｈｉｎｇＨＦＮ）数的变化。结果表明，治疗前平均ＨＦＮ为１０．９２±４．１１，明显高于正常对照组的４．８０±１．３４（Ｐ＜０．０５）；治疗后ＨＦＮ为７．６５±３．２３，与治疗前相比有显著减少（Ｐ＜０．０５）。表明高频心电图可作为诊断病毒性心肌炎和评价治疗效果的有效手段之一。

The change of the numbers of high frequency notching(HFN)were observed in 18 patients with acute virus myocarditis before and after treatment with Huangqi.The results showed:before treatment,the average number of HFN was 10.92±4.11 and was higher than those in control group(the HFN was 4.80±1.34)signifcantly(P<0.05).The number of HFN was decreased to 7.65-3.23 after treatment.There are significant difference from those before treatment(P<0.05).It is suggested that HFECG can serve as an effective means for diagnosing acute virus myocarditis and evaluating treatment effects.
