On presentation to the emergency department, she had a heart rate of 80 beats/min and blood pressure of 155/78 mm Hg. She had no family history of sudden cardiac death and a normal echocardiogram result. On telemetry, she was noted to have short runs of non-sustained wide complex tachycardia. An electrocardiogram was obtained (Figure 1).
