Mount Carmel Emergency Department Protocol for Early Cardioversion
of Hemodynamically Stable Atrial Fibrillation
Signs and/or symptoms of new onset
or recurrent atrial fibrillation (Afib)
Consider differential Dx for Afib: PE, CHF,
hyperthyroid, alcohol withdrawal, valvular
disease, infection, etc. Evaluate and treat
associated conditions as indicated
Consider complete blood count (CBC)
Consider basic metabolic profile (BMP)
Thyroid stimulating hormone(TSH) if new diagnosis
INR if on warfarin
Echo if no recent echo and possible to obtain OR can get as an outpatient
No
Excluded from Pathway:
•Known history of intracardiac thrombus
•Unclear duration of AFib or >48 hours of AFib while not on anticoagulation
•CHA2DS2-VASC score ≥ 5
•Signs of heart failure
•Known Ejection Fractur(EF) <30%
•Angina
•Acute MI within 4 weeks
•Stroke/TIA within 3 months
•Cr clearance <30
•Other comorbid conditions that require admission
Appropriate for Cardioversion (CV)
Preferred approach is procedural
sedation + DC CV
· Consider chemical CV if refusing DC
CV or not candidates for procedural
sedation in patients refusing DC CV.
