摘要
本文应用多普勒技术(彩色多普勒血流显像联合应用脉冲多普勒),体表心音图和临床听诊技术、对于二尖瓣、三尖瓣和主动脉瓣返流患者的检出率进行了对照研究。结果表明:以多普勒技术与心血管造影对照的检出率(100％)为基准,体表心音图的检出率为77～91％,临床听诊检出率为77～86％,影响临床听诊的因素主要是返流量的大小、持续时间的长短和返流方向。
To evaluate the sensitivities of combined color Doppler and pulsed Doppler,surface phonocardiography and auscultation in diagnosing valvular regurgitation,115 patients including mitral,tricuspid and aortic valvular insufficiency were studied.We found that the sensitivity is ranged from 77 to 9l percent in surface phonocardiography and from 77 to 9l percent in surface phonocardiography and from 70 to 86 percent in auscultaiton, but Doppler technique has a sensitivity of 100 percent. The role of identification by auscultation is influenced mainly by the quantity of regurgitation and also by the duration and direction of regurgitant jet. A significant difference between murmur group and no murmur group can be found.
