Thus, in part 1 there are chapters, some of them only a page or two, on electrocardiography, radiography, vibrocardiography (phonocardiography), cardiac catheterization, oxymetry, cardiac output estimations, ballistocardiography, blood pressure determination, pulse wave recording, circulation time, and blood volume. Part 2 describes the cardiac conditions mainly elucidated by the techniques outlined in part 1 and gives very brief descriptions of the diseases and abnormalities to be found at greater length in most books on cardiology.
