利用家兔作~+Gz过载暴露实验观察心电变化,用常规心电图描记术容易受到干扰,不易手工测算;即使能手工测算,也费时费事,我们利用数字处理技术和7T17信号处理机(日本三荣)等组成的分析系统进行分析,可克服上述困难。 我们使用信号处理方法有滤波和时域分析。用3～80Hz带通和50±1Hz陷波。对此,用7T17信号处理机的专用FFT程序能很方便地实现这一要求。首先,对经2ms时间间隔采样的原始时域信号求
The use of rabbit as a + Gz overload experiment observed ECG changes, with conventional electrocardiography susceptible to interference, difficult to manually measure; even manual calculations, but also time-consuming, we use digital processing technology and 7T17 signal processor (Japan three Wing) and other components of the analysis system analysis can overcome the above difficulties. We use signal processing methods for filtering and time domain analysis. With 3 ~ 80Hz band pass and 50 ± 1Hz notch. In this regard, with 7T17 signal processor dedicated FFT program can easily achieve this requirement. First, the original time-domain signal sampled at 2ms intervals is sought
