ABSTRACT
Purpose: A case of new onset bradycardia and hypotension following betel leaf consumption in combination with verapamil and metoprolol in an atrial fibrillation (AF) patient. Summary: A 66-year-old Nigerian woman presented to the emergency department for evaluation of multiple near syncope episodes with underlying AF and slow ventricular response. After initial evaluation, the patient disclosed she had ingested several betel leaves that morning. She was admitted for observation of severe, progressive hypotension and symptomatic bradycardia. Her past medical history included AF, type 2 diabetes, asthma, obesity, hypertension and hypothyroidism. Her home medications consisted of spironolactone, metoprolol succinate, and verapamil ER. Upon admission, her home medications were held. She received IV fluids and atropine .4 mg IV as needed for symptomatic bradycardia. Approximately 18 h following admission, her vital signs stabilized and her labs returned to baseline. She remained stable and was discharged with a recommendation to continue her home medications at prescribed doses with reduced doses of verapamil and metoprolol and to follow-up with her primary care provider. Conclusion: A patient with a history of AF developed significant hypotension and symptomatic bradycardia after betel leaf consumption resulting in an overnight critical care unit admission. The use of betel leaf is not common in the United States; however, practitioners should be cognizant of the use of complementary and alternative medications like betel leaf and incorporate this knowledge in patient evaluation. Patients consuming betel leaf or betel nut should be evaluated for cardiovascular effects as well as laboratory evaluation for organ damage.
