[Electrolyte disorders in the postresuscitation period after acute myocardial infarct]

Experiments on 25 dogs demonstrated that ion redistribution between the cellular and extracellular sectors develops during recovery after 5-min clinical death from acute coronary myocardial infarction. Early after resuscitation (5 min-9 h) sodium ion concentration in the cells increases, while that of potassium decreases. Later (9-24 h) part of potassium cations migrates from cells to cell-to-cell space and both cellular and extracellular potassium fractions decrease.
