探讨老年急性心肌梗塞（ＡＭＩ）患者ＱＴ离散度（ＱＴｄ）、ＱＴｃ离散度（ＱＴｃｄ）与泵衰竭的关系。方法６１例老年ＡＭＩ患者分为两组：泵衰竭组（Ｋｉｌｉｐ分级泵功能≥Ⅲ级者，ｎ＝２１）和对照组（Ｋｉｌｉｐ分级泵功能Ⅰ级者，ｎ＝４０）。分析患者入院时心电图的ＱＴｄ和ＱＴｃｄ。结果：ＱＴｄ、ＱＴｃｄ在泵衰竭组分别为（６４６±１６０１）ｍｓ和（７７３３±２０６０）ｍｓ，在对照组分别为（５２７５±１４５０）ｍｓ和（６０９８±１５９３）ｍｓ，二组间比较差异有显著性（Ｐ＜００５）。结论：ＱＴｄ和ＱＴｃｄ增大与ＡＭＩ患者的泵衰竭有关，ＱＴｄ和ＱＴｃｄ可作为评估老年人ＡＭＩ早期泵功能和预后的指标

To investigate the relationship between QT dispersion, QTc dispersion and pump failure in elderly patients with acute myocardial infarction (AMI). Methods Sixty-one elderly AMI patients were divided into two groups: pump failure group (Kilip grading pump≥Ⅲ, n = 21) and control group (Kilip grading pump, grade Ⅰ, n = 40). Analysis of patients on admission ECG QTd and QTcd. Results: The QTd and QTcd were (646 ± 1601) ms and (7733 ± 2060) ms respectively in the pump failure group and (5275 ± 1450) ms and ( 6098 ± 1593) ms, the difference between the two groups was significant (P <005). Conclusion: The increase of QTd and QTcd is related to pump failure in patients with AMI. QTd and QTcd can be used as indicators to evaluate early pump function and prognosis of AMI in the elderly
