    摘 要：目的：探讨心脏病患者24h心电图的变化。方法：通过分析386例心脏病患者的24h动态心电图情况，分析其各类心脏病与心律失常相关性。结果：各种心脏病中最为常见的是出现房性心律失常，而冠心病、高血压心脏病的室性心律失常发生率最高，但心衰与室性心律失常之间差异无显著性(P>0.15)，说明室性心律失常与左心功能减退无相关性。LOWN分级Ⅲ级以上室性心律失常易引发猝死。心房纤颤多见于风心病，其次为冠心病和肺心病；房室传导阻滞则多于病毒性心肌炎；无症状性心肌缺血(SMI)，在冠心病、心绞痛中发生率较高。结论：24h动态心电图监测对心律失常评估有着很大意义。

    Abstract：Objective：To explore change rules of 24 hours dynamic electrocardiogram. Method：Monitoring results of DCG of 386 cardiopathy patients were analysed. Results：Incidence rate of atrial arrhythmia was the highest in all kinds of cardiopathys, but incidence rate of ventricular arrhythmia was the highest in coronary heart disease(CHD) and hypertensive cardiopathy. There were no significant difference between heart failure and ventricular arrhythmia(P>0.15) and the results revealed there were not correlation between ventricular arrhythmia and left heart function failure. Ventricular arrhythmia patients who were Ⅲ grade of LOWN were apt to sudden death. atrial fibrillation usually occurred in rheumatic heart disease(RHD), CHD and pulmonary heart disease. Atrioventricular bundle usually occurred in virus myocarditis. Silent myocardial ischemia(SMI) usually occurred in CHD and angina pectoris. Conclusion：It had important significance that 24 hours dynamic electrocardiogram was used for assessing arrhythmia. ......
