【摘要】 目的:探讨老年肺心病患者急性期心律失常与并发症的关系。方法:回顾性分析186例老年肺心病急性期患者的临床资料,分析心律失常发生与心功能、低氧血症、电解质紊乱和并发症的关系。结果:与老年肺心病急性期患者NYHA心功能I~II级、PaO2>60mmHg、动脉血二氧化碳分压(PaCO2)<50mmHg、血钾3.5~5.5mmol/L比较,NYHA心功能III~IV级(61.9%比76.7%)、PaO2<60mmHg(59.0%比79.0%)、PaCO2>50mmHg(54.5%比94.3%)、低钾血症者(57.5%比94.2%)心律失常发生率明显升高;与无心律失常患者比较,发生心律失常者呼吸衰竭(36.7%比54.0%)、心力衰竭(31.7%比59.5%)、死亡(5.0%比16.7%)等发生率明显升高(P<0.05或P<0.01)。结论:老年肺心病患者急性期并发心律失常与多因素相关,且心律失常直接影响疾病并发症及预后。更多还原

【Abstract】 Objective:To explore the relationshipbetween arrhy thmia and complications in aged patients with pulmonary heart disease(PHD)duringacute phase.Methods:Clinical data of 186 aged PHD patients duringacute phase were retrospectively analy zed.The relationshipamongcardiac function,hy po xemia,electroly te disorders,complications and arrhy thmia were analy zed.Results:Compared with aged PHD patients with NYHA class I~II,PaO2>60mmHg,PaCO2<50mmHgand serum potassium 3.5~5.5mmol/L duringacute phase,there were significant rise in incidence rate of arrhy thmia in those with NYHA class III~IV(61.9% vs.76.7%),PaO2<60mmHg(59.0%vs.79.0%),PaCO2>50mmHg(54.5% vs.94.3%)and hy po kalemia(57.5% vs.94.2%);compared with nonarrhy thmia patients,there were significant rise in incidence rates of respiratory failure(36.7% vs.54.0%),heart failure(31.7%,59.5%)and death(5.0% vs.16.7%)in patients with arrhy thmia,P<0.05 or P<0.01.Conclusion:Arrhy thmia in aged patients with pulmonary heart disease duringacute phase is related to multiple factors,and it directly affects the complications and prognosis of disease.更多还原
