Rationale 1: Digoxin (Lanoxin) is used for atrial dysrhythmias.
Rationale 2: Excessive levels can produce serious dysrhythmias, since the action of the drug is to decrease the automaticity of the SA node and slow the conduction through the AV node.
Rationale 3: Subtherapeutic levels can cause the atrial dysrhythmia to continue, which can produce symptoms, but might not be lifethreatening or fatal.
Rationale 4: Interactions with other medications are common, but not monitored by drug levels.
