| 摘 要： | 应用小波转换的三维频谱分析技术，对４０只兔心电ＱＲＳ波进行分析，观察其三维心电频谱的特征。结果显示：正常兔心电ＱＲＳ波的三维频谱形态呈双侧对称的山坡状，频谱宽度约为２４０Ｈｚ，高频成分主要分布在ＱＲＳ波的中部，能幅随频率增加呈下降趋势，其中１００—１０００Ｈｚ与６０—１００Ｈｚ的能量比约为１０，１５０—２５０Ｈｚ与６０—１００Ｈｚ的能量比约为０３５，并证明性别和体重对心电ＱＲＳ波三维频谱各参数不产生严重影响。

| Abstract: | Electrocardiographic QRS complexes of 40 rabbits was analysed by three dimensional spectrum analysis based on wavelet transformation. The results show:electrocardiographic three dimensional spectrum of normal rabbits is a symmetric hillside in shape, spectrum width is about 240Hz. Major high frequency components is distributed in the middle part of the QRS complex, and energy amplitude is in decreasing trend as frequency increase. Energy ratio of 100-1000Hz and 60-100Hz is about 1.0, Energy ratio of 150-250Hz and 60-100Hz is about 0.35. Furthermore, sex and weight do not affect the shape and all parameters of three dimensional spectrum. |
