Network Five: Toxicology

In this exciting episode, we will be discussing the role of DigiFab in chronic digoxin toxicity before diving into an interesting case of organophosphate poisoning

ECG Case 109

84 year old male presents complaining of general lethargy, nausea, several episodes of diarrhea, and dizziness. Describe and interpret this ECG.

ECG Case 086

70 yr old male who presented with general lethargy and postural dizziness. He has a collapse the evening prior and recently had a diarrhoeal illness. His medications include warfarin, metoprolol, frusemide, allopurinol, colchicine and digoxin. Describe and interpret this ECG. LITFL Top 100 ECG

Digoxin poisoning

Acute digoxin poisoning manifests with vomiting, hyperkalaemia and brady-tachyarrhythmias potentially leading to death, whereas chronic digoxin toxicity is far more insidious, still with gastrointestinal symptoms but in addition bradycardia and automaticity on the ECG.

Troubling Tachycardia

An ECG case of Bidirectional ventricular tachycardia focusing on two main causes: digoxin toxicity & catecholaminergic polymorphic VT - CPVT

Digoxin toxicity: Management

Dr Betty Chan, emergency physician and clinical toxicologist, discusses the DORA trial and digoxin toxicity - 1 or 2 amps of immune fab only, no maths required - and explains why less is more.

Calcium, Digoxin Toxicity and ‘Stone Heart’ Theory

Administration of intravenous calcium has traditionally been considered a contra-indication for the treatment of hyperkalemia in the presence of digoxin toxicity. This is based on the ‘Stone Heart’ Theory: calcium may lead to an irreversible non-contractile state, due to impaired diastolic relaxation from calcium-troponin C binding

Digoxin Toxicity

Digoxin toxicity is characterised by gastrointestinal distress, hyperkalemia and life-threatening dysryhthmias, including increased automaticity and AV nodal blockade
