概要

• 論文の詳細を見る

• On 79 ECG tracings obtained from 31 uremic patients, the influence of serum Ca, Na, and K concentrations on the QT duration in ECG was analyzed by multiple regression technique. It was found that Ca and K had negative and Na had a positive effect on QT duration, although only the effect of Ca was reaching the statistically significant level. Since serum electrolytes had correlations with each other, they were orthogonalized and tested for significance once again. Still Na and K did not reveal significant influences by this procedure. However, the effects of Na and K on QT duration were as the same direction and magnitude as reported in older literatures.In the course of orthogonalization it was found that Ca and Na had negative influences on K. It seems that this fact presents a sound basis for the therapeutic use of Ca and Na salts in hyperpotassemia.
