摘要
目的：探讨急性心肌梗死患者心功能与QT离散度（QTd)的相关性。方法：对于18例伴有不程度心功能不全的急性心肌梗死患者，采用同步12号心电图测量其入院时，入院后第1、2周的QTd，并分析其与心功能的关系。结果：研究对象入院时心功能（Killip)为Ⅱ-Ⅲ级，QTd为87±18.62ms，入院后第1周的QTd为60.76±12.23ms,入院后第2周心功能为Ⅰ级，QTd为42.26±12.31ms；与入院时QTd比较，入院后第1、2周的QTd显著改善（P分别＜0.01、＜0.001)；心功能与QTd呈负相关关系。结论：急性心肌梗死患者心功能与QT离散度呈负相关关系，心功能越差，QTd值越大。
ve: To study the correlation between QT dispersion (QTd) and heart function in patients with acute myocardial infarction (AMI). Methods: QTd of 18 AMI patients with heart dysfunction was detected on hospitalization, and 1, 2 week after hospitalization by 12 leads electrocardiogram. Results: When hospitalization degree of heart function (Killip) of study object was Ⅱ~Ⅲ degree, their QTd was 87±18. 62ms; QTd was 42. 26±12. 31ms on 1 week after hospitalization; heart function of study object was I degree, their QTd was 42. 26±12. 31ms on 2 week after hospitalization. When compared QTd detected on hospitalization, QTd detected on 1, 2 week after hospitalization decreased significantly (P<0. 01, <0. 001 respectively); there were negative correlation between heart function and QTd. Conclusion: There is negative correlation between degrees of heart function and QTd in AMI patients with heart dysfunction.
