摘要:
目的 观察冠状动脉病变对QT间期及QT间期离散度(QTd)的影响。方 法 回顾性分析51例冠心病患者经皮冠状动脉腔内成形术(PTCA)治疗前QT间期和QTd及 PTCA治疗后QTd缩短情况，按冠状动脉病变进行比较。结果 ①PTCA治疗前QTd在 右 冠状动脉(RCA)病变比左前降支动脉(LAD)病变明显延长(P＜0.01);②PTCA治疗后RCA病变 QTd 缩短程度比LAD病变明显(50±11 ms对12±10 ms,P＜0.01)。③PTCA治 疗后 单支冠状动脉病变QTd缩短程度比多支冠状动脉病变明显(22±27 ms对5±17 ms,P＜0.05 )。结论 冠状动脉病变使相应部位QT间期延长,QTd增加。PTCA治疗后,QT间期缩短,Q Td减少。QTd缩短程度和病变部位有关。
Abstract:
AIM QT dispersion (QTd) were observed to the effect of diseas ed cor onary vessels site on chronic coronary heart diseases. METHODS A r etrospective s tudy with itself controls, QT interval and QTd changed in 51 patients with chron ic coronary heart diseases before and after treatment with percutaneous translum inal coronary angioplasty (PTCA). RESULTS ①Before PTCA therapy,th e increase of QTd of diseased right coronary artery (RCA) were significant compared with LAD (P＜0.01)。②Reduction of QTd of RCA were significant after PTCA therapy com pare d with LAD (50±11 ms vs 12±10 ms,P＜0.01)。③Reduction of QTd were sign ificant in patients with 1-vessel diseased of coronary artery after PTCA therapy compared with mul tiple vessels diseased of coronary artery (22±27 ms vs 5±17 ms,P＜0.05) . CONCLUSION The diseased coronary artery prolongs QT interval in correlative region, QTd was increased. After PTCA therapy,QT interval decreased , QTd should be lower rela tively. Reduction of QTd is related with the site (number,degree and so on) of t he diseased coronary artery.
