摘要
目的探讨实时三平面超声心动图(RT-3PE)测量正常人左室功能的准确性与可行性。方法应用RT-3PE测量36例正常人的左室每搏量(LVSV),并分别与M型Teichholz法、二维超声心动图Simpson法、多普勒主动脉瓣环血流量法所测的LVSV进行比较。结果RT-3PE与M型Teichholz法、二维超声心动图Simpson法、多普勒主动脉瓣环血流量法所测的LVSV不仅具有较好的相关性(r=0.774,0.932,0.786,P<0.01),并且上述4种方法所测LVSV之间无显著性差异(P>0.05)。结论实时三平面超声心动图能够准确地测量左室每搏量,为临床上快速、简便地评价左室功能提供了一种新方法。
Objective To evaluate the accuracy and feasibility of real- time tri - plane echocardiography（RT- 3PE） in measurement of left ventricular function. Methods Left ventricular stroke volume （LVSV） in 36 healthy volunteers were measured by RT- 3PE, M - mode Teichholz, two - dimensional echocardiography （2DE） simpson method and the product of aortic flow Doppler spectnan integral and aortic valvular area. Left ventricular stroke volume measured by RT- 3PE was compared with every measurement of three traditional methods.Results These results from RT- 3PE had good correlation with M - mode, 2DE and Doppler methods （ r = 0.765,0.890,0.804,P 〈 0.01）.Furthermore,there was no statistically significant difference among RT- 3PE and three traditional methods for LVSV. Consiusion RT- 3PE can accurately estimate LVSV and provide a new way for rapid, simple evaluation of left ventricular function in clinical study.
