Objective:To analyze the occurrence and therapeutic results of dialysis-related acute arrhythmias in pa-tients undergoing maintenance hemodialysis (HD).Methods:A total of 83 cases undergoing maintenance HD from Jun 2012 to Jun 2013 Were selected.Type,frequency and duration of dialysis-related acute arrhythmias Were recor-ded;risk factor and therapeutic results of dialysis-related acute arrhythmias Were analyzed.Results:The 83 HD pa-tients received a total of 8964 hemodialysis and 1046 acute arrhythmias occurred (11.67%)during hemodialysis,in-cluding 306 cases (29.3%)of premature ventricular beats,228 cases (21.8%)of sinus tachycardia,179 cases (17.1%)of premature atrial beats,138 cases (13.2%)of atrial fibrillation,81 cases (7.7%)of paroxysmal su-praventricular tachycardia,75 cases (7.2%)of ventricular tachycardia and 39 cases (3.7%)of sinus bradycardia. The rate of arrhythmia Was most during 1~2h after hemodialysis and sustaining to 4h.Logistic regression analysis indicated that risk factors of dialysis-related acute arrhythmias Were potassium disorder,heart disease (OR 4.46~18.96,P<0.05 all).After taking comprehensive treatment measures,the success rate terminating arrhythmia Was 95.3%.Conclusion:Dialysis-related acute arrhythmia is a frequent complication during hemodialysis,ventricular tachycardia rate may reach 7.2%,rate of acute arrhythmia reaches peak during 1~2h after hemodialysis,its risk factors are potassium disorder and heart disease, adequate treatment can effectively prevent and cure arrhythmia.%目的：分析维持性血液透析（hemodialysis， HD）患者透析相关急性心律失常的发生及治疗结果。方法：选择我院2012年6月～2013年6月维持性 HD患者83例，记录透析相关急性心律失常出现的类型，频率及时间，分析透析相关急性心律失常的危险因素，治疗结果。结果：83例 HD患者共透析8964例次，急性心律失常出现1046例次，发生率11.67％，按心律失常出现的频率，依次为室性期前收缩306例（29.3％），窦性心动过速228例（21.8％），房性期前收缩179例（17.1％），心房纤颤138例（13.2％），阵发性室上速81例（7.7％），室性心动过速75例（7.2％），窦性心动过缓39例（3.7％）；于透析1～2h心律失常发生率最高，并维持至4h；Logistic回归分析显示透析相关心律失常发生的危险因素是血钾紊乱、心脏疾患（OR 4.46～18.96，P 均＜0.05）；经采取综合处理措施后，终止心律失常的成功率为95.3％。结论：急性心律失常是透析的常见并发症，室性心动过速可达7.2％，心律失常于透析1-2 h达高峰，其危险因素为血钾紊乱和心脏疾患，适当的治疗可以有效防治心律失常。
