Abstract

The author studied the abnormal electrocardiogram which was obtained from a horse showing gas colic with heart dysfunctions, and also he recorded the phonocardiogram. The electrocardiogram exhibited several factors such as irregularity of impulse arising at the sinus node, incomplete A-V block; first degree of A-V block, ectopic focus in the auricle; diphasic P' waves, multiform ventricular premature beats; ventricular extrasystoles, and the paroxysmal ventricular tachycardia; short run type. These changes continued for 3 days with having close relation with each other. Phonocardiogram of the VPB showed remarkable changes such as decrease in amplitude and shortage in duration, which differ from those of normal curves. Discussion of the significance of the waves was also added.
