疑似冠心病患者运动平板试验中 QT间期及 T波峰末间期的变化研究
Change of QT Interval and Tpeak-Tend Interval of the Patients With Suspected Coronary Disease in Treadmill Test
摘要
Abstract
Objective To explore the changes of QT interval, QT interval of heart rate correction ( QTc interval ) , Tpeak-Tend interval ( Tp-Te interval) , Tp-Te/QT, Tp-Te /RR and Tp-Te/QTc of the patients with suspected coronary heart disease ( CHD) in treadmill test.Methods A total of 177 patients without CHD medical history who received treadmill test because of stethalgia in the First Affiliated Hospital of Wenzhou Medical University from January 2006 to May 2014 were analyzed retrospectively.The patients all received treadmill test and coronary arteriography, and according to treadmill test results and coronary arteriography results, they were divided into three groups: group with negative results of treadmill test and coronary arteriography ( group A, n =20 ) , group with positive results of treadmill test and negative results of coronary arteriography (group B, n=69 ) and group with positive results of treadmill test and coronary arteriography (group C, n=88) .We recorded the general data and the results of treadmill test of pre-test and exercise peak and the Duke scores of the three groups.Results The proportion of male and the smoking rate in group C were higher than those in group B (P<0.05) .QT interval, Tp-Te interval, Tp-Te/QTc of exercise peak were lower than those before treadmill test in group A ( P<0.05 ) .QT interval, Tp-Te interval Tp-Te/QT, Tp-Te /RR and Tp-Te/QTc of exercise peak were lower and QTc interval of exercise peak was higher than those before treadmill test in group B ( P<0.05) .QT interval, Tp-Te interval, Tp-Te/QTc of exercise peak were lower and QTc interval, Tp-Te/QT and Tp-Te /RR of exercise peak were higher than those before treadmill test in group C (P<0.05). The difference value of Tp-Te interval in group B was higher than that in group A ( P<0.05 ) .The difference value of QT interval in group C was higher than that in group A (P<0.05).The difference values of Tp-Te interval, Tp-Te/QT, Tp-Te/RR, Tp-Te/QTc in group C were higher than those in group A and group B ( P<0.05) .The Duke scores in group B and group C were lower than thaose in group A (P<0.05); the Duke score of group C was lower than that of B group (P<0.05). The difference values of Tp-Te interval ( r =-0.26, P <0.01), Tp-Te/QT ( r =-0.35, P <0.01), Tp-Te /RR ( r=-0.32, P<0.01) and Tp-Te/QTc (r=-0.17, P=0.03) were negatively correlated with Duke score.Conclusion QT interval, QTc interval, Tp-Te interval, Tp-Te/QT, Tp-Te /RR and Tp-Te/QTc of patients with CHD and non CHD before and after exercise are different, which may have a certain clinical value.关键词
