Summary
Propafenone overdose can cause severe symptoms like coma, seizures, and heart problems. This case highlights the critical management needed for such rare but dangerous antiarrhythmic drug toxicity.
Area of Science:
- Cardiology
- Clinical Pharmacology
- Toxicology
Background:
- Propafenone is a Class IC antiarrhythmic agent.
- Its use is infrequent, and overdose data is limited.
- Understanding propafenone toxicity is crucial for emergency management.
Observation:
- A patient presented with overdose of propafenone.
- Clinical manifestations included coma, seizures, bradycardia, hypotension, and conduction delays.
- This case represents a severe presentation of propafenone toxicity.
Findings:
- The patient's symptoms were consistent with propafenone's known cardiac electrophysiology effects.
- Management strategies were guided by the drug's pharmacology.
- This case adds to the scarce literature on propafenone overdose.
Implications:
- Clinicians should be aware of propafenone's potential for severe toxicity.
- Prompt recognition and management are vital for patient outcomes.
- Further research into propafenone overdose is warranted.
