1150例室性早搏的DCG检测与分析

目的：探讨室性早搏（ＰＶＢｓ）的发生规律及其与临床的联系。方法：对１１５０例有ＰＶＢｓ的２４ｈ动态心电图（ＤＣＧ）按有无器质性心脏病进行分组分析。结果：复杂性和频发性ＰＶＢｓ及短阵室速（ＶＴ）以心脏病者多发（Ｐ＜０００５及Ｐ＜００１）且以冠心病、心肌病等病变范围广，病变程度重者发生率高。ＶＴ均呈短阵发作，自行终止，多无明显症状。结论：复杂性、频发性ＰＶＢｓ及ＶＴ以心脏病者多发，并与心脏病变性质及严重程度有关。

DCG Detection and Analysis of Ventricular Premature Beat in 1150 Cases

Objective: To discuss the rules of ventricular premature beat (PVBs) and its relation with clinic Methods:24-hour DCG group analysis was conducted upon 1150 PVBs cases with or without organic heart diseases Results: Complicated or frequent PVBs and transient ventricular tachycardia (VT) were more likely to occur in patients with heart diseases, and most often in those with coronary heart disease or cardiomyopathy with extensive and severe lesion VT were transient, self-ended and without obvious symptoms Conclusion: Complicated or frequent PVBs and VT are more likely to occur in patients with heart diseases and are related to the nature and severity of the diseases
