摘要
为了了解递增负荷运动对心电频谱分析的影响,我们采用标准12导联引导心电信号,测试了30名大学生在递增负荷运动中的心电频谱图,所测得结果提示如下:频率成分能量比W1〔W1=E(100-1000Hz)/E(0-1000Hz)〕,W2〔W2=E(80-300Hz)/E(0-1000Hz)〕,在一、二级负荷运动后增大(P＜0.05),三级负荷后恢复到安静水平。
In order to find the changes of the Frequency Spectrum Electrocardiogram (FSECG) under progressively increased work lead exercise, 30 university students had the FSECG of 12 standard loads when they were doing exercises under progressively increased work load. The results are as follows. The rates of frequency energy W1 [ Wl = E ( 100 - 1000 Hz ) / E (0-1000 Hz)], W2 [W2 = E( 80-300 Hz) /E( 0-1000 Hz )] in FSECG increased after the first and second levels loading capacity ( P<0.05 ) . They resumed to the contrast levels after the third level loading capacity,
