100例起搏器安置前、后心音图的对比研究

A Comparative Study of Phonocardiogram in 100 Patients Before and After Pacemaker Implantation

目的：探讨起搏器安置前、后心音图的改变，以了解安置起搏器对心音图的影响及临床意义。方法：对在我院住院并安置有不同类型起搏器的患者１００例，进行了安置前及安置当天及安置７天的７个部位心音图的描记和分析。结果：起搏器安置后有９７％记录到心脏起搏音；６９例心室按需型起搏器安置后有４０％第三心音消失，５８％收缩期杂音减弱，３５％增强。１４例心房抑制型及１７例房室全能型起搏器安置前、后心音图改变不明显。结论：提示起搏器安置后，心音图可获得改善。

Objective:To investigate the changes in phonocardiograms after implantation of pacemakers,the influence of pacemakers on phonocardiograms,and their clinical significance. Methods:Phonocardiograms were taken and analyzed on the day of and 7 days after pacemaker implantation in 100 patients implanted various types of pacemakers. Results:Pacemaker sounds were recorded in 97% patients after implantation of pacemakers.In 69 patients with VVI pacemakers,S 3 disappeared in 40%,systolic murmur (SM) decreased in 58% and increased in 35% patients.However,no marked changes in phonocardiogram were found in 31 patients with types AAI ( n =14) and DDDR ( n =17) pacemakers. Conclusion:It is suggested that the phonocardiograms are improved after implantation of pacemakers.
