摘要
目的 探讨急性心肌梗死 (AMI)患者行经皮冠状动脉腔内成型术 (PTCA)后出现的再灌注性心律失常 (RA)与心室复极离散度 (QTd)的关系。方法与结果 对 36例AMI行PTCA手术患者术前术后 12导联心电图同步监测描记 ,发现 :①PTCA术后出现RA时 ,心电图上QTd值比术前有明显延长 (P <0 0 1)。②PTCA 1h后心电图QTd较术前缩短者 ,心律失常发生明显减少 (P <0 0 1)。结论 ①PTCA术后出现RA与QTd延长有关 ;②成功的PTCA 1h后心律失常的减少与QTd缩短有关。
Objective The purpose of this study was to assess the relation of the RA after PTCA and the QTd in AMI. Methods PTCA was performed successfully on 36 patients with AMI, 30 men and 6 women, mean age (55±15.2) years. QTd were obstained with a standard 12 lead ECG before and after PTCA.Results The results showed when the RA occurrenc after PTCA, that QTd were prolonged significantly compared with those before PTCA. Average QTd were prolonged from (45±9 8) ms to (65±7.9) ms ( P<0.01 ). One hour late after PTCA, the arrhythmias were reduced significantly, it is related to QTd shortened.Conclusion After PTCA, the larged QTd may be one of reasons for producing RA in patients with AMI.
