Digoxin antidote8/15/2023 ![]() Transvenous pacer wires may cause myocardial irritability (Kashani 2005).Consider Atropine 0.5 mg IV in bradydysrhythmia or high degree AV block.Do not wait for digoxin level if clinical presentation of digoxin toxicity is the likely cause.Chronic elevation of digoxin concentration with AMS, cardiac dysrhythmia, or severe GI symptoms.Acute ingestion of >4mg (>0.1 mg/kg) in peds.Digoxin level >10, 6 hours following ingestion.Any life-threatening digoxin related dysrhythmia.Evaluate for life threatening arrythmias.Theoretical idea of stone heart has been disproven (Levine, 2011).If hyperkalemia is present treat with Insulin, albuterol, and Calcium or follow your institution’s hyperkalemia protocol.Digibind is your treatment of choice in hyperkalemia in the setting of Digoxin Toxicity.Evaluate for hyperkalemia in acute toxicity as there is correlation with severity.For acute ingestions obtain levels on presentation and 6 hours after known ingestion.Evaluate for elevated digoxin levels in acute toxicity.Regular Afib in the setting of digoxin toxicity (Burns 2021) Impulses from the lower AV node will go down the left and right bundle branches leading to a Bidirectional Ventricular Tachycardia (Richter 2009) (figure 5).A higher degree AV block in AFib will produce a junctional rhythm which can produce a regularized R-R pattern leading to a regular AFib pattern (figure 4).Mobitz II is highly unlikely to occur as it originates below the AV node.With higher concentrations, Type I AV blocks may progress to a Type II Mobitz I pattern.Digoxin primarily affects the level of the AV node, decreasing conduction there and increasing the refractory period.Biphasic T wave: a prominent U followed by a flattened TĮCG changes in the setting of Digoxin effect (Burns 2021).PVCs is the most common arrythmia (Kashani 2005).Digoxin can cause a large variety of EKG abnormalities (Richter 2009).Digoxin Effect does not imply Digoxin Toxicity. ![]()
