To me, it was clearly atrial flutter with 1:1 conduction. The rate of 280 is just right for atrial flutter. The waves look like atrial flutter waves, NOT like a wide ventricular complex. Recently diagnosed with intermittent paroxysmal atrial fibrillation but no EKGs available to confirm.

She presented to the emergency department after a couple of days of chest discomfort. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate is about 130 bpm. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. The ECG below was recorded.
