摘　　要：应用ｌｏｇｉｓｔｉｃ多元回归分析方法，对１２５例心脏瓣膜替换术病人的１３项变量进行分析，探讨心脏瓣膜替换术后严重室性心律失常的相关因素。结果表明，严重室性心律失常发生率为２２％，无１例因心律失常死亡。单因素分析结果显示，术中及术后西地兰用量＞０．４ｍｇ，心功能３～４级，左心房内径较大及风湿性心脏病病人严重室性心律失常发生率较高。多因素分析结果显示，西地兰用量，心功能分级是影响术后严重室性心律失常发生的独立因素。提示减少术中和术后西地兰用量可能将显著降低术后室性心律失常的发生率。A study of factorts predicting postoprative ventricular arrhythmias with 13 parameters were performed.The results showed electrocardiogrphic and echocardiographic findings.28 (22%) patients had significant postoperative ventricular arrhythmias. There was no postoperative mortality related to these arrhytmias.Un ivariate analysis revealed that the dose of cedilanid>0.4mg used in and early after operation, NYHA functional class Ⅲ-Ⅳ and larger left atrium diameter were significant predictors. Logistic regression analysised that the dose of cedilanid and NYHA functional class were in dependent predictors of postoprative ventricular arrhythmias.In conclusion,reducing dose of cedilanid used in and after operation may decrease postoperative ventricular arhythmias.
