【摘要】 本文研究了正常小鼠组 (n =2 0 )和实验小鼠组 (n =1 0 )Ⅱ导联QRS波群功率谱与心率的相关性 ,发现正常小鼠组Ⅱ导联QRS波群中 1 0 2 — 1 0 3Hz、80— 30 0Hz的高频相对能量都与心率呈显著正相关 (P <0 .0 0 1 ) ;实验小鼠组Ⅱ导联QRS波群中仅 1 0 2 —1 0 3Hz的高频相对能量与心率呈显著正相关 (P <0 .0 5)。更多还原

【Abstract】 This paper analyzed the correlation between power spectrum of QRS complex and heart rate in lead Ⅱ of normal mice(n=20)and experimented mice(n=10).We found that the correlation between the relative power in the ranges of 80-300Hz and 100-1000Hz and heart rate in normal mice was very significant.While the correlation between the relative power only in the ranges of 100-1000Hz and heart rate was significant in experimented mice.更多还原
