摘要:
目的:明确肾脏短暂缺血预处理对急性心肌梗死(AMI)后QT间期离散度(QTd)变化的影响.方法:观察单纯AMI组(A组)和肾脏缺血预处理(RIP)组(B组)新西兰兔在AMI前后的QTd和室性早搏发生率，并行心内电生理诱发室性心动过速(VT)，对两组的指标进行比较，同时设It假手术组(C组)作对照。结果:3组在手术前QTd比较无显著性差异(P>0.05);C组手术前后QTd比较无显著差异(P>0.0 5)，在AMI后，B组QTd显著短于A组(P<0.01 ).结论:RIP可缩短AMI后QTd，并减少室性心律失常的发生。
Abstract:
AIM: To study the influence of transient ischamia on QT dispersion (QTd) after acute myocardial infarction (AMI). METHODS:QTd of group A (rabbits without RIP) and group B (rabbits with RIP) were measured after AMI, and electrophysiologic examination was made to induce ventricular tachycardia (VT). The gained indexes of two groups were analyzed and compared with each other. Group C (shame operation) was served as control. RESULTS :QTd of each group had no significant difference before operation(P>0.05).QTd of group C had no significant changes before and after shame operation(P>0.05).After AMI,QTd of group B were significant lower than that of group A (P<0.01). CONCLUSION:QTd and the rate of VT in group B (with RIP) was significant lower than that of group A (without IP).
