What Researchers Did
Researchers described a case of paroxysmal atrial fibrillation occurring in a patient after hyperbaric oxygen therapy for carbon monoxide poisoning.
What They Found
They found that a 78-year-old female patient with carbon monoxide poisoning (carboxyhemoglobin 42.6%) developed atrial fibrillation immediately after hyperbaric oxygen therapy. Her rhythm returned to normal sinus rhythm after amiodarone treatment.
Canadian Relevance
This study has no direct Canadian connection as it describes a single case from outside Canada.
Study Limitations
The primary limitation of this study is that it is a single case report, which limits generalizability of the findings.
