New Concepts in Echocardiography

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 beco...
