摘　　要：使用国产前置放大器和 A/D、D/A 转换卡和 Doctor-852程序,按 Langner 方法记录分析59例病毒性心肌炎患者的高频心电图,并与60例正常人比较。患者组 QRS 波群6个导联切迹总数超过3个者38例(64.4%),显著高于对照组4例(6%;P<0.01);患者级 QRS 最高频率均值63.2Hz,显著高于对照组(42.1Hz;P<0.01)。从20至100Hz 频率段进行分段频率比较,患者组从40至100Hz 段的频率百分比较对照组增加5～17%,这些改变对诊断心肌炎患者心肌缺血有重要意义.To study the special changes in high frequency ECG in acute viral myocarditis fifty-nine Patients and sixty normal subjects were analyzed by China-made equipment and Doctor-852 computer programme.The resultes indicated: 1.the notching number in patients group (averaging 4.7 in six leads) were greater than in normal subjects group (1.2.P<0.01); 2.the average highest frequency in six leads (63.2±10.2Hz) was Higher too compared with normal subjects;(42.1±9.7Hz) 3.the Power percent of high frequency from 20 to 100Hz in patients group was 5-17% higher than that in control groupe These changes might have important significance to dingnose ischemia in patients wiih myocarditis.
