摘要/Abstract

摘要： 目的: 研究急性心肌梗死（AMI）并发室性心动过速患者T波峰末（Tp-Te）间期的变化,并探讨Tp-Te间期变化对AMI并发室性心动过速的潜在诊断和预后评估价值。方法: 126例急性ST段抬高型心肌梗死患者,根据是否并发室性心动过速分为研究组（59例,并发室性心动过速）和对照组（67例,未并发室性心动过速）。所有患者均在入院后12小时内行经皮冠状动脉介入术（PCI）治疗,分别检查患者PCI术前、术后7天的心电图,计算Tp-Te间期,并分析AMI并发室性心动过速患者的危险因素。结果: 研究组患者心肌梗死急性期的Tp-Te间期明显长于对照组（P<0.01）;AMI并发室性心动过速患者恢复期的Tp-Te间期明显短于急性期（P<0.01）;Logistic回归分析显示,Tp-Te间期是AMI并发室性心动过速的独立危险因素。结论: Tp-Te间期对AMI并发室性心动过速的诊断和预后判断具有潜在的临床指导意义。

Abstract: Objective: To study on the changes of Tpeak-Tend (Tp-Te) interval in patients with acute myocardial infarction (AMI) complicated with ventricular tachycardia, and investigate the potential value of Tp-Te interval changes in diagnosis and prognosis evaluation of AMI complicated with ventricular tachycardia. Methods: 126 acute ST-segment elevation myocardial infarction patients were divided into study group (59 patients, AMI patients complicated with ventricular tachycardia) and control group (67 patients, AMI patients without ventricular tachycardia). All the patients were treated with percutaneous coronary intervention (PCI) within 12 hours after admission. The electrocardiograph of all the patients were detected before PCI and 7 days after PCI respectively and the Tp-Te interval was calculated, as well as the risk factors of AMI complicated with ventricular tachycardia were analyzed. Results: In acute phase, the Tp-Te interval of patients in study group was obviously longer than patients in control group (P<0.01). The Tp-Te interval of AMI complicated with ventricular tachycardia patients in recovery phase was significantly shorter than the patients in acute phase (P<0.01). Logistic regression analysis showed that Tp-Te interval was an independent risk factor for AMI complicated with ventricular tachycardia. Conclusions: Tp-Te interval has potential clinical guiding significance for diagnosis and prognosis of AMI complicated with ventricular tachycardia.
