[Influence of blood potassium variations on changes in electrocardiographic patterns during oral glucose tolerance test].
In 45 apparently healthy subjects an OGTT was performed and glucose, insulin, potassium and sodium were measured at fixed intervals. A standard EKG was recorded at the beginning and at the end of the trial. K+ levels steadily decreased reaching their lowest value 60 to 120 min after insulin peak. Na+ levels did not change. In those subjects whose final EKG showed some worsening, the ratio final to initial K+ levels, unlike glucose levels, significantly decreased (p less than 0,01). The hypothesis is given that many clinical pictures of coronary heart disease, so often encountered during OGTTs, may depend on K+, rather than glucose, unbalance.
