title: [Electrolytic and electrocardiographical correlations under 7% oxygen in nitrogen in dogs (author's transl)].
abstract: Electrolytic concentrations in plasma and electrocardiographic parameters in dogs have been studied by means of lineal and canonical correlations, after the animals have been submitted to 7% oxygen in nitrogen for three hours. At the end of hypoxia there appeared hypokalemia, increased T wave potential, low R wave and enlargement of ST segment and PQ interval. The coefficients of lineal correlation between Mg++ levels in plasma and R wave potential and those of Na+ and QRS interval were reversed at the final stages of hypoxia.
