Approximately 90% adult patients with proven digoxin toxicity have serum digoxin levels greater than 2
This heartbeat is often caused by atrial fibrillation
The risk of digoxin toxicity is potentiated in elderly patients and in those with renal impairment (as digoxin is predominantly renally cleared), electrolyte disturbances (eg
