慢性肺源性心脏病并发心律失常的临床特征及病因分析

Clinical features and etiological factors of chronic pulmonary heart disease with arrhythmia

目的:探讨慢性肺源性心脏病并发心律失常的临床发病特点.方法:选取2012-05/2014-05我院心内科收治的慢性肺源性心脏病患者168例作为研究对象,分为心律失常组(n=110)和心律正常组(n=58),总结慢性肺源性心脏病诱发心律失常的类型,同时分析对比两组心律失常的相关因素.结果:本研究中肺源性心脏病并发心律失常比例为65.48%(110/168),心律失常类型主要以窦性心动过速、过缓、不齐为主.心律失常并发及严重程度多因心力衰竭、肺部严重感染、缺氧、酸碱平衡、电解质紊乱等因素引发,与心律正常组相比,差异有统计学意义(P<0.05).结论:慢性肺源性心脏病潜在心律失常发病率较高,且可能受多种因素诱发,了解其心电图特点有利于该病的临床诊断和预防.

AIM: To investigate the clinical characteristics of chronic pulmonary heart disease with arrhythmia. METHODS:A total of 168 patients with chronic pulmonary heart disease with arrhythmia admitted into our hospital from May 2012 to May 2014 were selected as study objects, with 110 cases in arrhythmia group and 58 cases in normal group. The type of chronic pulmonary heart disease that could induce arrhythmia was summarized which and the related factors of arrhythmia in two groups were compared and analyzed. RESULTS: The proportion of pulmonary heart disease complicated by arrhythmia was 65.48% (110/168), and the main arrhythmia was sinus tachycardia, bradycardia and arrhythmia. The factors such as heart failure, severe lung infection, hypoxia, acid?base balance and electrolyte disturbance could induce arrhythmia. There was a statistically significant difference between normal heart rhythm group and arrhythmia group ( P<0.05) . CONCLUSION:The incidence of cardiac arrhythmia in chronic pulmonary heart disease is high and may be induced by many factors, and it is helpful for clinical diagnosis and prevention.
