Electrocardiograms (ECG) were recorded from 83 clinically healthy dogs by computerized electrocardiography (CE). The results obtained are summarized as follows. 1) The diagnosis made by CE hardly coincided with the true diagnosis even when the chest unipolar leads and wave pattern were corrected to such extent that they might be similar to those of human beings. 2) The results of diagnosis by CE were low in reproducibility. 3) The heart rate determined by CE was reliable until it was 180 per minute. When it exceeded 180, a big error was noticed in it. 4) The smaller the amplitude, the larger the error between the amplitude determined by CE and that actually measured. The fluctuation of the basic line was also influenced considerably. The R and T waves of large amplitude were measurable. 5) Duration and interval determined by CE were almost always inexact, being longer than those measured actually. 6) It seemed necessary for the application of CE to animals for diagnosis not only to change the existing program but also to make improvement in various points.
