- W4212846598 abstract "For several decades following Laënnec's invention of the stethoscope there was a rich output of literature concerning the sounds of the heart. Experimental, clinical and postmortem observations were drawn on to explain the mechanism and meaning of normal and pathologic sounds. Since the advent of the x-rays and the electrocardiograph the subject has been presented from a new point of view. Graphic studies of the heart sounds by direct phonocardiographic methods and especially with electrical amplification have come to the front. This volume is the result of experimental and clinical study along these lines. Technic is described. The mechanism and graphic registration of normal sounds are well considered. In the last part more than a hundred pages is devoted to sounds in pathologic states —valvular lesions, gallop rhythm and various disturbances of rhythm. Many excellent illustrations, most of them original, help to explain the text. There is a good bibliography." @default.
