摘要
目的探讨心肌缺血与QTc离散度（QTcd）的关系，方法分析30例经潘生丁试验核素心肌灌注显像证实冠心病心肌缺血患者的QTcd，以20例潘生丁试验核素心肌灌注显像正常者作为对照。结果冠心病组潘生丁试验前后QTcd均显著大于正常组（P＜0．001），冠心病组潘生丁试验后QTcd显著大于试验前（P＜0．05）。结论慢性或急性心肌缺血均可引起心肌复权不均一，导致QTcd增大。
Objective To explore the relationship of myocardial ischemia and QTc dispersity (QTcd). MethydsMyocardial ischemia in 30 patients with coronary heart diseases was confnmed by persantine radionuclide myocardial perfusion imaging, analysed their QTcd, compared the control group with 20 normal imaing Patients. Results QTcd incoronary heart disease group was obviously larger than control (P < 0. 001 ), there was a larger QTcd in coronary heartdisease group after persantine test than than before (P < 0. 05 ). Conclusion chronic and acute myocedial ischemia couldbring regional variation in myocardial electrode recovery, and increased QTcd.[
