摘要

为探讨冠心病患者的Ｑ－Ｔ离散度与冠脉狭窄程度及左室大小的关系，观察了６５例冠状动脉单支狭窄＞６０％的冠心病患者，其中不伴左室增大者３７例，伴左室增大者２８例，正常对照组３５例。结果发现，伴有和不伴有左室增大的冠心病组的Ｑ－Ｔ离散度较正常组显著增大，ＱＴ离散度与冠脉狭窄程度及左室大小呈正相关。提示Ｑ－Ｔ离散度可作为评价冠脉狭窄程度及左室肥大的参考指标之一。

Abstract

The purpose of this work was to study the relationship of QT dispersion to the degree of coronary artery stenosis and to left ventricular dimension. The QT dispersion(QTd) in 65 patients with single-vessel coronary artery stenosis(>60%)and 35 normal subjects was investigated.Among the patients were 28 with enlarged left ventricles. The results showed that QTd in stenosis patients with and without enlarged left ventricle was significantly longer than that in normal subjects

and that QTd had a positive relation to the degree of coronary artery stenosis and the left ventricular dimension. This indicates that QTd could be an index for the evaluation of degree of coronary artery stenosis and left ventricular dimension.
