本装置是能够与心脏两维剖面图象配合,同时能实时显示EKG(心电图)波形的系统。这样EKG波形就能直接与心脏腔体容积的变化相对照。把一台用于产生心脏C型扫描剖面图象的超声探测仪,一个EKG逻辑电路,一个EKG监视器电路与超声探测仪电路组合在一起,在同一个示波器屏幕上产生一条连续的垂直扫描线以显示EKG波形,而心脏图象也同时显示出来,这样就可以连续检测心脏腔体容积变化和EKG波形周期性之间的同步关系。
The device is capable of with the two-dimensional cross-sectional images of the heart, while real-time display EKG (ECG) waveform system. This EKG waveform can be directly compared with the changes of the volume of the heart cavity. An ultrasound probe used to generate a C-scan profile of the heart, an EKG logic, an EKG monitor circuit, and ultrasound probe circuitry were combined to create a continuous vertical scan line on the same oscilloscope screen To display EKG waveforms, and heart images are displayed at the same time, so that the synchronization between the volume changes of the heart cavity and the periodicity of EKG waveforms can be continuously detected.
