An Analysis of 161 Cases of Cardiac Infarction with ABC Electrocardiographic Studies and 36 Necropsies

Preventive Tail‐tip Inoculation of Calves Against Bovine Contagious Pleuropneumonia

“…In order to restrain the rather excitable young calves for this purpose, it was usually necessary to narcotize them lightly by the intravenous injection of pentobarbitonum sodium, at the rate of 5-6 mg per kg body weight. The three-dimensional ABC electrocardiograDhic display (Trethewie, 1951(Trethewie, , 1953 was used, since studies in man and mice indicated that in pathological states this yields more complete information than other displays (Trethewie, 1954(Trethewie, , 1958Trethewie and French, 1955).…”

Pulmonary Stenosis and Right Ventricular Pressure

“…It has also been shown vastly superior to the standard lead system in indicating RVH (Harris, 1961). It has also been shown to give a positive diagnosis in all 161 of a series of cardiac infarction where 18% were missed by the standard leads (Trethewie, 1958). Both Russian and American astronaut investigators have shown special value of lead A (of the ABC display) and also of a lateral Y lead of some relation to lead B of the ABC display.…”
