It should be judged by the clinical manifestation. Treatment of digoxin toxicity almost depends on the clinical severity. This article is talking about how to diagnose whether it is digoxin poisoning, and the treatment after diagnosis for a case to provide medical professional references. 64 THE JOURNAL OF TAIWAN PHARMACY Vol.27 No.4 Dec. 31 2011
