A woman in her 30s with active bulimia was brought by ambulance to the emergency department after a syncopal event that followed 1 hour of palpitations and intermittent lightheadedness. When emergency responders arrived, the patient was responsive but groggy. An electrocardiogram (ECG) in the field demonstrated a regular wide complex tachycardia. En route to the hospital, 6 mg of adenosine followed by 12 mg of adenosine were administered intravenously, without a change in her rhythm.
