Representative ECG of limb lead/chest lead interchange. (A) A 12-lead ECG recorded from a healthy male volunteer. (B) ECG with 4 limb leads and 4 chest leads reversed. The right arm, right foot, left arm, and left foot leads were connected to V1, V2, V3, and V4, respectively, and vice versa. Note that all chest leads including V5 and V6, the leads that stayed in place, displayed a QR pattern followed by negative T waves. aVF = augmented vector left foot; aVL = augmented vector left arm; aVR = augmented vector right arm.
