电记波图是以曲线形式记录心脏血管搏动的一种 X 线检查法,比 X 线记波摄影优越,因为记波摄影的波形小,记录时间短,记录速度慢,不能把裂隙放得与心脏搏动方向平行一致,更不能同时记录象心电图等之生理曲线。Lian 氏于1934年及 Heckmann 氏于1936年分别使用电记波图;1945年 Henny氏使用光电倍增管,改进了器械与技术,才使电记波图广泛应用。电配波图的原理和检查方法电记波器是由以下部件组成:1.心脏搏动接受器;主要是光电倍增管,使光线转为
Echocardiography is an X-ray method of recording cardiac vessel beats in the form of a curve, which is superior to X-ray imaging. Because of the small waveform of record photography, short recording time, slow recording speed, Heart beat parallel to the direction of the same, but can not simultaneously record the physiological curves such as ECG. In 1934, Heinzmann and Heckmann used the echocardiogram in 1936. In 1945, Henny’s photomultiplier tube was used to improve the instruments and techniques to make the application of electropotentigraphy widely. Electrowoward wave principle and inspection method Electro-wave filter is composed of the following components: 1. Heart beat receptor; mainly photomultiplier tube, so that light into
