Figure 3 This dot diagram shows voltage amplitude distribution of flutter wave in lead I. Receiver-operating characteristic analysis found that a cutoff point of >0.07 mV has a sensitivity (Sens) 89.3% and a specificity (Spec) of 100% in differentiating between reverse typical atrial flutter (group 1) and upper loop re-entry (group 0). AFL = atrial flutter.
