摘要
本文采用结扎家兔左室支不同部位的方法,对梗塞范围与频谱分析、峰—峰电压值(Vp-p)的关系进行了观察,结果表明:(1)心肌梗塞后>100Hz成分减少,频带分布能量比值(W)与梗塞范围呈负相关。(2)结扎左室支后Cp-p值降低,与梗塞范围呈负相关。(3)W值和Vp-P值之间无直线相关关系。FirslAffiliatedHospitalofHenanMedicalUniversity.

different parts of the left coroaary ventricular branchs(LVB)of rabbitswere ligated,the relat
ionship between the infarct ion size(IS)and spectral ana-lysis aud voltage values of peak
peak(Vp-p) was observed. The results demon-stratcd:(1)The content of>100Hz decreescd after
infarction, the energy ratioof frequency-band distribution(W values)was negatively correlated
with IS;(2)The Vp-pvalues was decreesed after ligated LVB. Vp-p values was nega-tively
correlated with the IS;(3)There is no linear correlation between the Wvalues and the Vp-p
values.
