【摘要】 目的:探讨急性心肌梗死相关动脉溶栓再通后QTcd的变化及临床意义。方法:对64例发病6h内的患者行静脉溶栓治疗,按梗塞相关动脉有无再通分为再通组(n=45)和未通组(n=19)。结果:溶栓后再通组QTcd与溶栓前及未通组溶栓后比较明显缩小(P<0.01);溶栓后24h再通组并发恶性室性心律失常较未通组显著降低(P<0.01)。结论:成功的溶栓治疗可明显缩小QTcd,降低恶性室性心律失常的发生率;QTcd变化也可作为判断溶栓疗效及预测恶性室性心律失常危险性的一项指标。更多还原

【Abstract】 Objective: To investigate the change and clinical effect of QTcd in patients of acute myocardial infarction after ronlbolic repatency in correlate artery. Methods:All 64 patients who got the disease within 6h were given rombolism intravenous drip, and then they were assigned to repatency group( n =45) and non-repatency group( n = 19) according to whether there were repatency or not in correlate arteries. Results:QTcd of repatency group after rombolic therapy was evidently minified than that before ronlbolic therapy and that of non-repntency group (P< 0. 01); 24h after ronlbolic therapy, the supervention of malignant ventricle arrhythmia of repatency group was obviously lowered than non-repatency group (p<0.01). Conclusions: Successful ronlbolic therapy can evidently minify QTcd. The change of QTcd can be an index for curative effect and prognose of risk of malignant ventricle arrhythmia.更多还原
