| 摘 要： | 目的 探讨 70岁以上的老年急性心肌梗死 (AMI)患者室性心律失常与QTcd的关系。方法 回顾性单盲法分析 10 0例 70岁以上老年急性心肌梗死 (AMI)发病 2 4h内首次心电图未校正的QT离散度(QTd)、心率校正QT离散度 (QTcd)。结果 5 5例QTcd大于 6 0ms患者室性心律失常发生率明显高于QTcd小于 6 0ms的患者。结论 老年急性心肌梗死QTcd增高是导致室性心律失常的原因之一 ,早期测定QTcd是防止心律失常导致猝死的重要检测内容

| Abstract: | Objective To discuss the relationship of ventricular arrhythmias with QTcd among those patients older than 70 age who suffered from acute myocardial infarction(AMI).Methods Retrospective single blind method was used to analyze the inspect result of un regulated QT discrete rate(QTd) and regulated QT discrete rate(QTcd) of ECG of heart attack in 24 hours in 100 cases with acute myocardial infarction(AMI) among those older than 70 age.Results In 55 cases,the incidence of ventricular arrhythmias in those of QTcd greater than 60ms is higher than those of QTcd less than 60ms.Conclusion The increase of QTcd in acute myocardial infarction is one of the cause of ventricular arrhythmias.Detecting QTcd in early stage is an important mean to prevent sudden death from cardiac arrhythmias. |
