Clinical Scenario: The 12-lead ECG shown in the figure was obtained from a 57-year-old man. Review of this ECG should raise (induce) several questions in your mind. Which questions? Answer this even though you have not been provided with any clinical information about the patient.

Interpretation: The ventricular rhythm is irregularly irregular. A supraventricular etiology is confirmed by recognition that the QRS complex is narrow in all 12 leads. Despite the irregularity, this rhythm does not represent atrial fibrillation because organized atrial activity is present. Instead, the regular sawtooth pattern of atrial activity in the inferior leads identifies the ...
