Abnormal vital signs in patient's following toxic exposures can suggest underlying toxidromes. Differential diagnosis of abnormal signs
Toxicological causes of cardiac arrest
The differential diagnosis of toxicological causes of cardiac arrest are many and varied. It is useful to consider the causes in terms of mechanism.

Evidence-based Toxicology
Much of what we do in toxicology is because we think it works, not because we know it works. Clinical toxicology has traditionally been based on animal studies, case reports and case series based on clinical observation rather than clinical trials
Iron Overdose
Iron overdose can have local gastrointestinal effects as well as characteristic systemic toxicity (metabolic acidosis, liver failure, shock and multi-organ failure). Risk assessment is based on the amount of elemental iron ingested
Plant Toxicity
Severe toxicity from plants is rare in humans; risk assessment is often difficult - plant identification may be difficult; - toxin quantification may be impossible
