| 书目名称 | New Concepts in Echocardiography | | 编辑 | N. Bom | | 视频video | | | 图书封面 |  | | 描述 | Present day cardiology is in great need of non invasive, non toxic, and inexpensive devices which permit the delineation and visualization of normal and abnormal intracardiac structures, the calculation of intra cardiac volumes and study of contractility of the cardiac muscle. All of these may become within our reach if the principles outlined in this book and the preliminary clinical experience can be validated in general cardiac practise. The gist of one of the devices (visualization of the in vivo moving heart recorded on a short motion picture) is available to the interested reader on a 16 mm filmstrip. Rotterdam, June 1972 P. G.
