Methods The mitral (M1) and tricuspid (T1) valves componented of the first heart sound (S1), the aortic (A2) and pulmonary (P2) valves componented of the second heart sound (S2) were detected by short-time Fourier transformation spectrogram and Shannon engergy, in the high frequency resolution circumstance.

在频率分辨率较高的情况下，利用短时傅立叶变换声谱图和香农能量，提取出第1心音(S1)的主要成分二尖瓣关闭音(M1)、三尖瓣关闭音(T1)及第2心音(S2)的主要成分主动脉瓣关闭音(A2)、肺动脉瓣关闭音(P2)。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.
