What's the link between hypoglycaemia and arrhythmia?

a Japanese study  published online in Diabetes Care suggests a link between Qtc prolongation and severe hypoglycaemia potentially explaining some of the adverse outcome from very tight blood sugar control. I'm not sure however I can unpick this effect from the hyopthermia and the hypokalaemia also observed in this group. Do you think hypoglycaemia alone can cause heart rhythm abnormalities or are other 'mediators' necessary? sadian
