Evaluation of Myocardial Function Using Power Indices,f the ventricle. An acute increase of the afterload, for instance, combined with no change of contractility results in a reduction of the ejection fraction and of the velocity of fiber shortening .

New Developments in Video Systems: Camera Tubes and Storage Devices,tation possible. While the stereo technique also appears to be very suitable, so far it has only been applied in individual cases . Instead of the cut film changer with its frame speed limitation, nowadays, without exception, the image intensifier cine technique is used for documentation. Only in
