摘要
目的分析１１２例扩张型心肌病（Ｄｉｌａｔｅｄｃａｒｄｉｏｍｙｏｐａｔｈｙ，ＤＣＭ）患者心脏结构改变与心律失常的关系。方法用常规心电图、２４小时动态心电图、超声心动图、胸部Ｘ线拍片及血清学分析等检查房性心律失常及室性心律失常及左心房、左心室结构。并排除高血压性心脏病和其他心脏病、糖尿病、电解质紊乱及急性感染所致心律失常。结果ＤＣＭ患者室性心律失常发生率多于房性心律失常，且较早发现，其中恶性心律失常与左室增大有关，房性心律失常与左房肥大有关，左室壁变薄组左室增大较左室壁正常及肥厚组多见。老年ＤＣＭ患者心律失常发生率明显高于非老年ＤＣＭ患者，且与左室及左房增大有关。结论在ＤＣＭ患者，用上述检查（特别是动态心电图和超声心动图）不仅可获得左心室结构改变的信息。
Objective To analyse the relationship between changes of cardiac structure and arrhythmias in dilated cardiomyopathy(DCM).Method 112 patients complicated with atrial,ventricula arrhythmics and their left atrial & left ventricular structure were studied with electrocardiogram,dynamic cardiogram,chest X ray and serological analysis.Arrhythmias caused by hypertensive heart disease and other heart disease,diabetes,electrolyte disorder were excluded.Results The examination showed that ventricular arrhythmias occured more frequently than atrial arrhythmias(88.1% and 74.6% respectively) at the early stage of DCM.Serious ventricular(atrial) arrhythmias correlated to the left ventricular(atrial) enlargement.The incidence of left ventricular enlargement is more frequent in the thin left ventricular wall group than normal left ventricular wall & hypertrophy group.Arrhythmia in old patients with DCM not only were more frequent than that in patients with DCM <60 years old,but also were related to left ventricular & atrial enlargement.Conclusions Above examination(especially dynamic electrocardigraphy and echocardiography) not only obtains information of left ventricular structure changes,but also contributes to diagnosis & differenial diagnosis of arrythymia in DCM.
