Drunk potassium channels

Abstract

We report the case of a 42-year-old woman who was admitted due to alcohol induced dehydration leading to cardiac symptoms. On physical examination severe hypokalaemia and long QT syndrome were apparent. During potassium (K +) supplementation we simultaneously observed QT interval recovery. This is the first report of continuous documentation of the QTc duration during serum K + rise, highlighting the necessity of electrocardiogram documentation and serum potassium correction in appropriate patients. © 2011 The Author.
