The right and left arm leads have been reversed in the top tracing. Note the negative P wave in I which suggests that this is not a form of dextrocardia. Note that the precordial leads are unchanged by this error, which also excludes dextrocardia. Note that aVF changes little, aVL switches with aVR, II switches with III.
