[Relation between the blood potassium and blood glucose responses and electrocardiographic changes, specifically the T wave, during the oral glucose tolerance test].
As previously showed by the Authors, serum K+ levels significantly decrease during OGTT. Moreover, two possible patterns were separated: a) monophasic decrease ("M" type curve) causing a mild but continuous down-slope, possibly physiologically more relevant, and b) polyphasic decrease ("O" type curve) causing a sharp down-slope followed by a rebound to normal K+ levels. In 10 of 12 M type subjects (83%) electrocardiographic changes were shown after OGTT, comparative to only 9 out of 16 O type subjects. The Authors believe this to be suggestive of a heavier impact of kaliemic changes on to myocardial function in M type curves. The hypothesis needs further analysis.
