目的观察分析扩张型心肌病(dilated cardiomyopathy,DCM)24小时动态心电图监测(twenty-four-hour ambulatory electrocardionraphic monitoring也称Holter)改变。方法 49例确诊为DCM患者,行Holter监测,分析这些患者24小时动态心电图发生的改变。结果所有患者Holter均有异常改变,以室性心律失常最常见,共47例(95.92%);房性心律失常次之,共38例(77.55%);ST-T改变14例(28.67%),传导阻滞13例(26.53%)等。且心功能越差,复合性心律失常越多见,左房内径(leftatrialdiameter,LAD)越大,复合性房性心律失常越多见,左室舒张末期内径(Left ventricularend diastolicdimen-sion,LVED)越大,复合性室性心律失常越多见。结论 DCM患者24小时动态心电图表现多种多样,心律失常发生率高,且多样、易变。DCM患者早期进行心电图及Holter检测对早期发现心律失常及预后有重要意义。
Objective To observe and analyze the changes of 24-hour ambulatory electrocardionraphic monitoring (also known as Holter) in dilated cardiomyopathy (DCM). Methods 49 cases were diagnosed as DCM patients, Holter monitoring, analysis of these patients changes in 24-hour Holter. Results All patients had abnormal changes of Holter. The most common ventricular arrhythmias were 47 cases (95.92%), followed by 38 cases (77.55%) with atrial arrhythmias, 14 cases (28.67%) with ST-T changes, , Conduction block in 13 cases (26.53%) and so on. The worse heart function, the more complex arrhythmia, the greater the left atrial diameter (LAD), the more complex atrial arrhythmia, left ventricular end diastolic diameter (LVED) more Large, complex ventricular arrhythmias see more. Conclusion DCM patients with 24-hour Holter performance varied, the incidence of arrhythmia, and diverse and variable. Early DCM ECG and Holter detection of early detection of arrhythmia and prognosis of great significance.
