室性早搏的起源定位及其临床意义的探讨

目的通过对室性早搏（VPS）起源进行分析，了解VPS起源及其临床意义。方法将305例VPS病例按起源、临床诊断、年龄、伴发心电图改变等项分为若干组进行对比。结果在非心脏病组中，右室VPS的发生率是左室的4倍，心脏病组中左、右室的YPS发生率相近似，双室VPS均见于心脏病组者。不同年龄组中，以41～60岁组的VPS患者最多，且此组临床以冠心病、高血压者居多，〉60岁组以冠心、肺心、高血压居多，21～40岁组以风心病多见；伴发的心电图其它改变也随着年龄的增长而有增多趋势。结论室性早搏的起源并不能决定VPS的性质，需结合其它临床资料多方参考分析，才能确定其临床意义。在器质性心脏病伴发频发、多源、多形、连发、甚至短阵室速（VF）时，即有明确临床意义。

Objective In an attempt to investigate clinical significance and relationship between ventricular premature beat and origin, we studied origin of ventricular premature beat. Methods To evalualed protopathic relationship of among each groups of ventricular premature beat, bssed on origin of ventricular premature bear, the 305 cases patients were sepauated 8 groups. Results The results showed that incidences of ventricular premature beat were obvious higher right ventricular than left ventricular among no cardiopath groups , incidences of right ventricular and left ventricular were similar in cardiaopath groups, incendences of ventricular premature beat of right ventricular and left ventricular occured in cardiopath. Incidences were inequality among each age, class, cardiopaths. Conclusion The studies indicates that quality of ventricular premature beat were not correlated with origin of ventricular premature beat ,the clinical significance of ventricular premature beat were ascertained by synthesis and analyses of combining clincal dats. There are clinical significance in organic cardiopaths with fequent ventricular premature beat, multifocal ventricular premature beat, multiformed ventricular premature beat, paired ventricular premature beat, ventricular tachycardia.
