2. Figure 1
The patient's initial ECG obtained from the emergency department showed atrial flutter with 2:1 atrioventricular conduction (shown by the arrows in V1) at a ventricular rate of 125 beats/min. The absence of a sawtooth pattern in the inferior leads suggests atypical flutter at an atrial rate of 250 beats/min.
