Analysis of dialysis-related acute arrhythmias in patients undergoing maintenance hemodialysis / 心血管康复医学杂志

ABSTRACT

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.
