• Generally accepted is the fact that the electrocardiographic changes are induced by many factors: such as excercise, the taking of food, smoking, change in posture and breathing. The purpose of this study is to analyze the electrocardiographic changes and to classified the mechanism of the electrocardiographic changes after the administration of glucose, the important sourse of energy for the heart. MATERIALS AND METHODS Subjects were 41 normals (35 males and 6 females of ages 19 to 54, averaging 29.9) who have had no history of cardiac, diabetic, hepatic, nephrotic disease, disorder of thyroid grand, severe acute infectious disease, operation of stomach and gallbladder and also who have normal fasting electrocardiogram. Methods: Subjects were prohibited from eating after last supper, and in the next early morning electrocardiogram and phonocardiogram were taken and serum levels of glucose, potassium, natrium and calcium were measured and 100 grams of glucose was administrated orally with 400 to 500 ml of water. Same tests were repeated in 30, 60, 90, 120 and 180 minutes after glucose ingestion. In , 2 cases insulin and NEFA were measured. In 19 cases Katz Index was calculated. In some cases, insulin and glucoseintravenously and KCl orally were given. In dogs, glucose, combination of glucose and insulin, that of glucose, insulin and asparate-K were given intravenously. RESULTS Blood sugar: In all cases, blood sugar level was within normal ranges with WILKERSON'S criteria. Serum electrolytes: Serum potassium was significantly decreased 30 minutes after glucose ingestion and then slightly increased. Serum natrium was decreased in 30 minutes and became normal in 60 minutes. Serum calcium was not changed. Insulin and NEFA: Insulin level was maximum in 30 minutes and then lowered gradually. NEFA continued lowering for 3 hours. Katz Index: It was increased in 11 cases, decreased or unchanged in 8 cases.
