title: Dose response in vivo to digoxin in normo-and hyperkalaemia: associated biochemical changes.
abstract: The effect of digoxin, at two different inotropic levels, was examined in normo- and hyperkalaemic dogs. For similar inotropic responses, normo- and hyperkalaemic dogs had similar levels of (Na+, K+)-ATPase inhibition and microsomal-bound digoxin.
