心肌缺血与P波离散度关系的探讨

RELATIONSHIP BETWEEN MYOCARDIAL ISCHEMIA AND P WAVE DISPERSION IN CORONARY HEART DISEASE

目的探讨心肌缺血与P波离散度(Pd)、P波最大时间(Pmax)的关系。方法观察组为54例冠心病(CAD)患者,对照组为26例类似心绞痛发作的非冠心病患者,观察其胸痛发作时及缓解后的Pd、Pmax。结果冠心病组心绞痛发作时与缓解后Pmax、Pd值相比差别有显著意义;冠心病组心绞痛发作时Pd、Pmax与对照组相比差别有意义;冠心病组与对照组Pd、Pmax及LVEF相比,结果具有意义及显著意义。结论Pd、Pmax受冠心病心肌缺血影响较显著。*

Objective To understand relation between myocardial ischemia and P wave dispersion degree （PD） ,P wave maximum（Pmax） during angina pectoris in Coronary heart disease（CAD）. Methods Anginalike symptoms group were observed PD,Pmax during and after the relief of pain. Results PD,Pmax showed significance between CAD group and control group ,PD increased significandy during angina compared to the asymptomatic period. Conclusion Pmax,PD are significantly influenced by myocardial ischemia during angina peetoris in CAD
