| 摘 要： | 急性心肌梗塞（ＡＭＩ）时梗塞部位与正常心肌之间存在缺血区域，缺血区心肌细胞跨膜动作电位复极化延缓，各部位心肌细胞复极不一致，表现为心室复极的离散度增加，心室易损期延长，恶性室性心律失常的发生率增高，ＡＮＩ的病死率也相应增高。本文观察了３６例ＡＭＩ患者发病２或３日的ＱＴ、ＪＴ离散度，并与２５例健康人作对照，结果表明：ＡＭＩ组ＱＴｄ、ＪＴｄ较对照组显著增大（Ｐ＜００５），发病后早期死亡组（８例）ＡＴｄ、ＪＴｄ较存活组（２８例）明显增大（Ｐ＜００１）。认为用ＱＴｄ、ＪＴｄ增大来评价ＡＭＩ患者的早期预后有一定意义，且ＱＴｄ、ＪＴｄ监测方法简便、易测、无创伤性。

| Abstract: | It is reported that the value of increased QT interval dispersion,JT interval dispersion in early acute myocardial infarction in this paper.We random 36 acute myocardial infarction patients on the third day,whose QT dispersion (QTD) and JT dispersion (JTD) were analysesed.Meanwhile compared with those of 25 normal individula.The results showed that QTD and JID of AMI patients were significant greater than those of normal group(P<0.05).The QTD and JTD of AMI patients whodied subsequently before discharge were significant greater than those of AMI patients who survived.These indicated that there is certain value by means of analysis the QTD and JTD to predict subsequent mortality. |
