OBJECTIVE
Myocardial swelling occurs during endotoxic shock. The hypothesis that swelling-activated Cl- current (ICl,swell) activates during endotoxic shock was tested.
METHODS
Endotoxic shock was induced by intravenous lipopolysaccharides (10 mg/kg) in guinea pigs. The effects of ICl,swell blockers on the cardiac action potentials in papillary muscles and on the ICl,swell in single ventricul...
