T-wave normalisation and U-wave disappearance occurred sooner in the intervention group than in the control group after potassium supplementation. The rate of increase in potassium concentrations gradually became similar in both groups. The initial blood potassium concentration, method of potassium supplementation, potassium supplement dose, and 24-hour urinary potassium excretion significantly affected the rate of increase in blood potassium concentrations after supplementation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The efficacy of enteral potassium supplementation is equivalent to that of supplementation with high intravenous potassium concentrations in elderly patients with chronic heart failure and moderate to severe hypokalaemia.
