• This research is concerned with the effects of varying the dietary levels of potassium on body weight, blood electrolytes, electrocardiogram in young dog. Dogs were fed purified diets containing varying levels of potassium salts.(1) Diet-induced potassium deficiency in dogs resulted in lowered weight gain.(2) The degree of development of the electrocardiographic changes were in general parallel to the levels in the serum potassium. When serum potassium levels decreased to 4.0mEq./L. or less, the T wave was usually decreased in height or inverted, the U wave in left precordial lead was frequently seen, ST segment slightly depressed, and P-R and Q -T intervals were rarely prolonged.(3) When serum potassium levels rose above 6.0mEq./L. the T wave was consistently peaked and increased in height, especially in lead VL. However, these levels did not rise above 6.2mEq./L. On the other hand, potassium concentration in feces of high potassium diet group increased at same time.(4) Arrhythmias sometimes appeared in hypo-and hyperpotassemia.(5) Within 3 to 8 weeks most of potassium deficient dogs developed paralysis of legs.
