总结 15 9例冠状动脉 (简称冠脉 )造影且心电图及临床资料完整的病例 ,为探讨冠脉病变严重程度、病变位置及冠心病介入治疗对QT离散度 (QTd)及校正QT离散度 (QTcd)的影响。结果 :冠脉狭窄≥ 70 %对QTd及QTcd影响明显 (P <0 .0 5 )而冠脉狭窄 <70 %对QTd及QTcd无明显影响 ;冠脉病变所处位置对QTd及QTcd无明显影响 ;介入治疗后QTd及QTcd明显变小 ,P <0 .0 5。结论 :冠脉病变所处位置对QTd及QTcd无明显影响 ,病变严重程度及介入治疗对QTd及QTcd有明显影响。
In order to investigate the severity of coronary lesion, the location of the lesion and the interventional treatment of coronary heart disease (QTd) and QTcd (QTcd), the results of coronary angiography and electrocardiogram (ECG) )Impact. Results: Coronary stenosis≥70% had a significant effect on QTd and QTcd (P <0.05) and coronary stenosis <70% had no significant effect on QTd and QTcd. Coronary lesions had no significant effect on QTd and QTcd ; QTd and QTcd significantly decreased after interventional treatment, P <0.05. Conclusion: The location of coronary artery lesion has no obvious effect on QTd and QTcd. The severity of the disease and interventional therapy have significant effects on QTd and QTcd.
