摘要
目的 :探讨心肌缺血与 QTc离散度 (QTcd)的关系。方法 :测量 80例平板运动诱导的心肌缺血患者的QTcd并与 5 0例正常人作对照。结果 :缺血组运动后 QTcd显著高于正常对照组 (P <0 .0 0 1) ;而对照组运动前后QTcd变化无显著性差异 (P >0 .0 5 )。结论 :心肌缺血是 QTcd增大的重要因素 。
To investigate relationship between QTc dispersion and myocardial ischaemia.Method:QTc dispersion in 80 patients with exercise induced myocardial ischaemia and 50 normal controls were observed and compared.Result:QTc dispersion was greater in patients with ischaemia after exercise than in normal controls (P< 0.001 ).Treadmill exercise could increase QTc dispersion in patients with myocardial ischaemia (P< 0.001 ). There was no significant difference in QTc dispersion before and after exercise in normal controls (P> 0.05 ).Conclusion:Results revealed that increased QTc dispersion might result from myocardial ischaemia during exercise test. It could serve as an indicator to judge result in exercise stress test.
