Data are percentage (95% CI) for change values or beats/min (95% CI). AF = atrial fibrillation; HR = heart rate; RVR = rapid ventricular response.
Adjusted for HR at the time of initial AF medication administration, age, sex, race or ethnicity, congestive heart failure and asthma or COPD history, mean arterial pressure, sequential organ failure assessment score, vasopressor or inotrope use, magnesium level, potassium level, white blood cell count, troponin I level, hemoglobin oxygen saturation, and presence of mechanical ventilation and hemodialysis.
