Prolonged cardiotoxicity from poison lilly (Veratrum viride)

A 51-y-o otherwise healthy male presented to the emergency department 45 min after ingesting a soup made with boiled "leeks". Physical examination was significant for severe vomiting depressed mental status, and sluggishly reactive 2-3 mm pupils. Heart rate was 30 bpm and bp was 40/p mmHg requiring atropine and fluid resuscitation. After 60 min substernal chest pressure was noted and an ECG showed new V2-V6 ST segment depression. Recurrent hypotension required the use ofa dopamine infusion. At this time, the regional poison control center botanist identified a sample of the ingested material as Veratrum viride. The patient improved slowly over the next 24 hours, although bradycardia and heart block persisted for approximately 48 hours.
