| 摘 要： | 测定了６４例老年心肌缺血（ＭＩＳ）患者和２１例心肌梗塞（ＭＩ）患者心电图的ＱＴｃ间期和ＱＴｃ离散度（ＱＴｃｄ），并与心血管神经官能症（ＣＶＮ）及正常老年人进行比较；探讨ＱＴｃ、ＱＴｃｄ与致命性室性心律失常（ＦＶＡ）、心原性猝死（ＣＳＤ）的关系；分析ＭＩ不同部位的ＱＴｃｄ变化以及稳定性心绞痛（ＳＡＰ）和不稳定性心绞痛（ＵＳＡＰ）的ＱＴｃｄ差异。结果：老年女性患者ＱＴｃ较男性长（Ｐ＜０．０５），而ＱＴｃｄ两者无差异；老年ＭＩＳ患者ＱＴｃ和ＱＴｃｄ较正常组明显延长（Ｐ＜０．０１）；ＭＩ前壁、下壁和后壁３组ＱＴｃｄ无明显差异（Ｐ＞０．０５）；ＵＳＡＰ患者ＱＴｃｄ较ＳＡＰ长（Ｐ＜０．０５）。

| Abstract: | he authors measured the QTc interval and QTc dispersion in 64 elderly cases with myocardial ischemia(MIS) and 21 cases with myocardial infarction(MI) and compared with those of the cardiovascular neurosis(CVN) patients and normal elderly.We inquired into the relationship between increased QTc interval, fatal ventricular arrhythmia(FVA) and cardiac sudden death (CSD). The results showed that QTc was greater in the female than in the male( P <0 05) QTc and QTcd were longer in patients with MIS than in healthy controls( P >0 01).There were no obvious difference between QTcd in anterior, inferior and posterior MI.QTcd was greater in unstable angina pectoris than instable angina. |
